Even considering -maximum- uptime of the +healing buff proc, Ring of Harmonic Beauty probably only has around 9 less +healing than Band of the Eternal Restorer, while it would have around 9 more Mp5 and a bit more Stamina. So, I would definitely lean towards the Ring of Harmonic Beauty x2 (if possible in live.)

I'm late on this, and I realize I'm continuing the derail, but my approach is a slight modification on a healing pool: "let's assume we burn X amount of mana (casting some cycle of spells) in 30 seconds and see how much healing we can put out each cycle".

The idea is that if you have more regen and therefore more mana, you'll just cast more often and keep the burn rate constant. (And overheal more, but I do that anyway just because I don't want to have multiple heart attacks per raid.) The one thing I'm unhappy with about it is that in that case you can't really assume a set FSR%, since inherently in order to cast more and "use" more regen your FSR% goes up.

And yes, that ring is extremely sexy.

Actually, you lose 120 healing by going [Staff of Immaculate Recovery] (as well as the healing proc effect) instead of [Crystal Spire of Karabor] and [Scepter of Purification]. I normally go for more balanced all around stats rather than just straight up healing, but the tradeoff just isn't worth it in this case. Not too suprising I suppose, ilvl 151 for the 1h option vs 141 for the staff. And considering how good the mace is for shamans it might not be an option for you depending on what Illidan drops. We get the mace and stupid bow every time it seems, so it was a pretty easy choice for me. The new alchemist stones makes me very happy, we still haven't gotten a single [Memento of Tyrande]. I was contemplating if I wanted to use [Scarab of the Infinite Cycle] post 2.4 if Illidan didn't start droping some trinkets, but the new alchemist stone is even better than it.

With the Sunwell I'm pretty sure that I'll go back to staves though, Golden Staff of the Sin'dorei is far better than Archon's Gavel and some offhand.

Why are you saying "how good the mace is for shamans"? I assume you mean chain heal, but one can argue the mace is just as good if not better for circle of heal.

ThankGod should do the trick.

I haven't used it in a while myself. Unfortunately, I'm at work and can't check to see if it works. It flashes the screen and will warn you of a few priest procs in a curiously breathy female voice.

Staves are a much less attractive option when you can use shields and with the options avalible we still had shamans with light's justice at that point. Most guilds won't be killing Vashj that many times and hammer of atonment are likely going to be picked up by paladins before anyone else.

The original post is still entirely valid in 2.3.2; I'm not going to update it until 2.4 goes live and we actually *know* what the final regen mechanic is. If it's as currently set on the PTR, we'll all be rethinking all of our gear and playing methodologies, since regen will be a non-issue (for pretty much anyone).

I'll start work on the update, and try to have it ready for 2.4.

With the new alchemist stone using [Earring of Soulful Meditation] is no longer the no brainier I was expecting. So using the current regen formula and assuming 650 int I set out to see what some realistic regen numbers for the earing are. I'll preface this by saying these numbers are primarily for my own situation and the test server is subject to change.

forumla used: Regen_mp5 = 5*0.00932715221261 * sqrt(Int) * Spirit
sqrt 650 int = 25.5
356.76 mp5
x 4 = 1427.054 over 20 seconds
/24 = 59.458 mp5 max over the 2 min cd
x .3 = 17.8 mp5 minimum if clicked every cd with 0 oofsr time.

Thats obviously very rough and quite a range.

Over the course of a 7 minute fight I'd say I would on average get 1 click with 10-12 sec oofsr, 2 uses with 5 seconds oofsr max. and obviously some time spent waiting for inner focus or a clearcasting proc.

so that 60 seconds total 20 at full and 40 at min
8 x (356.76 x .3) = 856.2
4 x 356.76 = 1427

[top] 2283.2 mana returned from the trinket
/84

27.18 mp5 over 7 minutes assuming 30% oofsr during the trinket effect
thats under imo fairly standard use of the trinket with a minimum amount of "waiting around time"
If the fight was say 8 minutes long the mp/5 drops to 23.78

ex no 2 same fight but I get average 10 seconds oofsr per click.
30 seconds oofsr 30 seconds ifsr
6 x (356.76x .3) = 642.2
6x 356.7 = 2140.2

[top] 2782
/84

33.1 mp5 in 7 min encounter assuming 50% oofsr during trinket effect
/96 = 28.97 mp5 in an 8 min fight

I could do more examples but it prolly still wouldn't be what "you" think is the norm so by all means do your own calculations, but it looks pretty clear to me that if you can't get off at least 10 seconds oofsr per click of earing theres going to be better options available both in terms of regen and particularly in regen and + healing.

All in all it bottoms out around 18 mp5 but under any fight where it would matter I would say anything above 30-35 mp5 is unrealistic due to either taking long breaks from casting or wasting time waiting for clearcasting/IF, and obviously if your int isn't as high that will affect the results too. Just an example a using 529 int the oofsr mp5 drops to 329.8 or a loss of 4.5 mp5 over 2 minutes assuming 100% oofsr during the trinket's proc ( or simply a 7% loss in regen).

Anyway hopefully some people find it interesting and/or helpful, and I apologize for any sloppy or inconsistent rounding > >
Edit: added bolding for tldr types.

I already am in love with my [Alchemist's Stone] I cannot wait for the upgraded version of it!

Now just to get an [Eye of Gruul]

I have been working on the holy priest healing spreadsheet I posted some time ago to include the haste and manareg changes and to add sunwell loot. Next to the main feature of calculating what healing output is possible for given encounter/talent parameters the sheet now features a new section to assemble your gear. Roughly speaking it's not the same spreadsheet anymore due to the massive changes both visible and invisible to the user. I'd be really happy to get some feedback on the implemented features. The Excel sheet is completely unlocked so feel free to poke around.

Version 1.1 (for 2.4 PTR)
Version 0.7 (for 2.3), if you want to compare some of the data

Refer to the Info worksheet for a short introduction how to use this spreadsheet. Due to the new nature of the sheet it won't be much hassle to change the manareg formula if blizzard decides not to totally kill mp5 for us priests and druids (and "overpower" us with massive spirit/int based regeneration).

Vurrin, you may also want to keep in mind that with raid buffs it contributes 22 +healing via Spirit over time, bringing it up to 88 +healing on average, plus the Mp5. I'm also not sure you factored in the multipliers to the 300 Spirit, which result in it being 346.5 Spirit for non-Humans and 381.15 Spirit for Humans.

The main benefit of the Earring has always been on-demand regen for long delay points. Using it while Clearcasting/Inner Focusing is a secondary benefit at best. In fact, the primary reason I wear it is for Innervates on Bloodboil / Council, and "/emo /rage /rp" on Illidan (every transition when he's going blah-blah).

Having said that, I'm seriously debating dropping herbalism for Alchemy, because the new stone is *the* best trinket in the game assuming chain-potting, and I can easily chain pot. Mana pots don't cost much. And if I don't need the mana, and don't use the pots ... then the Sliver's bonus would be wasted as well, as (mostly) would Memento's. Which makes it functionally equivalent.

My ranking of trinkets in 2.4 goes something like:

1. New Alchemist's Stone
2. [Memento of Tyrande]
3. Blackened Sliver of the Naaru
4. [Earring of Soulful Meditation]
5. [Rejuvenating Gem]

... and I'm quite looking forward to switching #5 for #2 or #1.

You really would rank the Rejuvenating Gem about [Eye of Gruul] ?

First of all, rejuvenation gem has 22 more +healing. Second, that proc has 2% rate which is awfully little. Even when chaincasting greater heal you only cast around 24 in one minute. 2% proc chance / cast and you may not get a proc for 3 to 4 minutes straight. No procs means no extra mana gained.

Yes, "it is likely" you may say, but chances are one thing a healer can't afford. Passive gain is much better than one gained from "a chance to" -effect. No matter how big the chance, unless its 100% it may never proc.

Band of the Eternal Restorer - Spells - World of Warcraft

According to that effect has a 10% proc chance. When I tried to get a proc while idling in a city, I spent my whole manapool casting greater heals and I didn't get one single proc. No, it was not on an internal cooldown. Often when I do something like that it procs, yes. But often is not always and definately not when I want to.

Short version: 2% proc rate is ridiculously low.

Eye of Gruul is a very good trinket if you are specced CoH and the encounter makes it possible to use alot of CoH. Then the 2% procc is worth about 20 mp5. For everything else I would also prefer Rejuvination Gem.

The Eye of Gruul is a rather situational trinket; In normal situation where GHeal ends up being the main spell, it's proc chance of 2% is too low to really make a big difference, and the +healing is low compared to several other trinkets out there. That said, once you start using CoH it becomes rather nice, since it counts every person hit as a separate cast. Assuming you hit 5 people, the chance for a proc then becomes 1-0.98^5 = 10%, which is pretty nice with heavy uses of CoH. That said, outside of those situations I will definitely use Redeemer's Alchemist Stone + [Earring of Soulful Meditation], and I haven't done enough theorycraft on the amount of mana the [Eye of Gruul] will save in the aforementioned situations.

Keep in mind that stat multipliers aren't additive, so it's 1 * 1.1 * 1.05 (* 1.1), so 1.155 or 1.2705 depending on race. Minor point, but 300 Spirit is a big number so it tends to matter.

I feel like the main issue with Alchemist Stones is the assertion that you have to use mana pots to get the most use out of it. This a) doesn't always present itself and b) costs money/time/resources. Perhaps b) is a minor point nowadays, but still a point nonetheless. a) is really more my point, because honestly I only use about 2-3 mana potions a week--if that--and hardly see much reason to use them. So, for me, the Alchemist Stone use effect would probably be fairly useless most of the time.

While the trinket is quite nice, it's also coming at a time when Priest regen is making yet another quantum leap...meaning that, at least for current content, I don't expect to be using mana potions all that often.

One could argue that doing so would let you gear into more +healing or something like that by dropping regen, but most of our "best" items are so packed with Spirit that having high gear-based regen is hard to avoid.

No doubt it's a good trinket, though. However, as someone who doesn't have Alchemy it's really not good enough to coax me into dropping Tailoring or Enchanting at this point. But perhaps I'm just against to the principle of spending 4-6g per fight in order to get some use out of my gear.

Assuming that you have a good hit rate with your CoH and pretty much all you do is spam CoH, the proc is worth much more than 20 mp5. If you're smart about chaining it with an inner focus (it's basically the equivalent of clearcasting for CoH priests) and possibly even the Earring of Soulful Meditation, it should be worth at least 50 mp5. I absolutely hate the trinket when I accidentally leave it equipped on a single-target healing fight though...

Just grabbing my guild's WWS from TK last night, on an 8 minute Solarian fight, I had 13 "Healing Trance" procs. At 1.625 procs per minute, even with my CoH talented down to 405 mana (it's not because my spec is weird, but lets just say it is) the proc alone is saving me 54.8 mp5. This is not even counting Inner Focus tricks to stay in the 5sr.

On trash, my numbers are even slightly better. I got 50 Healing Trance procs over 30 mins of trash, so 1.667 procs per minute - 56.25 mp5 (TK trash is almost ideal CoH spam conditions cause your entire raid is smashed into a tiny hallway, taking constant AoE damage).

For raw mana regen nothing is going to beat [Eye of Gruul] on fights like Solarian, Najentus, Mother, Bloodboil, Illidan, RoS, Void Reaver... and that's just mp5 calculated without using OFSR mana regen.

Triple procs is a guranted OFSR, but besides triple proc, you can double proc and wait 1 second, or single proc and then IF or something.

Also, if you're using hunters, the proc rate goes up since it also hits hunter pets. 4 Hunters for last week's Bloodboil was fun.

Key word for all of this.... with CoH.

The way I see it, the encounters where you want the regen from these trinkets are ones in which you would be using mana potions anyway. If you're not then what difference is the mana returned from this one trinket going to make?

Oh that pet thing is awesome. I always wondered why my numbers were so close to the "ideal" numbers I got from napkincrafting, and I guess it's because I was always assuming a 10% proc rate, when really it can be 12% or even more on groups with pets... WTB more huntards!

Our raids regularly have Hunterx3/Shaman/Druid or Hunterx3/Shaman/Demo Lock groups, which make for fun spamming of CoH. Especially in the last setup, I can get 9 viable targets in a single heal--which is resonably fun.

In regard to the chance of it proc'ing per cast, you could easily look at it as the chance of not triggering in a given set of attempts as it is 5 independant rolls. 0.98^5 in a group of 5 is only a 9.61% chance to proc per cast rather than 10%. (It is 4% lower in comparison, so worth considering.) Given 3 Hunter pets (8 targets), you would increase to a 14.93% chance to proc.
