Surge of Light
"Your spell criticals".

Thus spells which hit more than one target (and thus have a higher chance of getting a single crit) have a higher chance of proccing SoL.

fake edit: waaaay too slow.

Nice work. A few comments on the Intellect versus Spirit issue:

1. I think there's a clerical error in the Mp5 from replenishment, which should be .0125 times the 15 mana you get from 1 point of intellect, i.e. 0.1875 instead of 0.0125

2. There is a fairly technical post on the mathematics of "how much spirit / intellect should I have" here. A lot depends on the amount of Mp5 you assume you'll actually realize in practice from each point of int. However, based on that previous discussion, a crude estimate of the relative value of intellect relative to spirit would be:





If the value you get is 1.0, intellect and spirit are equally valuable to your mana regeneration. If the value is 1.5, then intellect is 1.5 times more valuable than spirit. If it's 0.5, then intellect is half as valuable as spirit, etc.

3. The rapture returns from divine aegis per point of intellect at level 80 have been worked out in another post as:



Assuming 20k-30k mana, 20-30% crit rate, and 3K-5K raw HPS (including overheal, but only counting crittable heals), a fairly conservative estimate would be 0.1 Mp5 per point of intellect.

Have you tried clicking on a lolwell when there's 25 people standing on top of it though?

As it stands, lightwell is a solution with no suitable problem.
- You can't be in a hurry: not only do you need to have some time to move to it and click on it, it also takes time to heal you up.
- Everyone is always in a hurry: either trying to dps/tank/heal as hard as they can, or needing That Fat Heal Right Now Or Else.
- If people are spread out, it's unusable: too far to run for the average raid member.
- If people are clumped up, it's unusable: you can't click it as it's neatly embedded inside a tauren derriere.

If something is unusable in practice, its theoretical output is immaterial.

In my dream world, lightwell would be implemented like a "healing void zone" which only a blind man could miss - healing the lowest-health targets that step into it (thus requiring no clicking), up to a maximum of X healed total.
That sort of implementation would definitely make it very useful for the scenario you describe, and X being high enough could justify the spell having as long a cooldown as it does.

If you put a lightwell down in the right place, there should be no issue clicking it (it has a range - it's not like you need to stand on top of it to click it). The bubble on KJ is exactly the kind of situation its great for - a lot of people who are taking damage / are about to take damage, in one place, with no reason not to change target to click it.

If people use it properly, it saves a hell of a lot of healing. It's like quite a lot of talents now - situational, but incredibly useful in that situation.

I've been 9-10 manning Magtheridon recently on my priest with some friends, and using it for the MT to use during the end of earthquake/before blast nova/etc, and for an offtank to use during the start of the fight, it is very useful as an extra heal while others are unavailable/out of range/etc. Making people aware that it's there to be used is one of the biggest challenges, but once you do it can easily save lives. I can see it being of more use in 10 mans when you only have 1-2 "full" healers, but you should still get some use out of it in 25's (enough to justify the point at least).

This would be true if intellect give 1mana. Right value without kings is: 15 * 0.0025 * 5 = 0.1875mp5.

It's VERY situational I'm aware. But i wouldnt call it unusable. In fact I think I may try it tonight. Placement will be an issue im sure. BUT if it saves even one life then it was worth the cast time/mana.

Ahhhhh to be in a perfect world. I think blizzard has made it abundantly clear by now that they intend lightwell to be a mid level rarely useful talent. I highly doubt that will change anytime in the near future. That being said I can still think of decent uses for it. Toss one right behind the mellee, or somewhere close to the warlocks so they can LT without healers having to watch/worry about them. Again Limited uses, BUT I think its a viable and useful alternative if you can use it intelligently.

Fair points dukes/Zomgdie.
Other examples of the well being useful could be plonking it down next to your warlocks on a Kaz'Rogal-like drain fight, or wherever your Brutallus's Burn victims stand. Loatheb sounds rather like a job for the lolwell too.

I do however think that at the very least its cooldown needs to be around 2 minute mark in order for it to be of tactical, rather than just novelty, value.
And I still do have a dream

I know you mean this in like the heuristic touchy-feely "I'm a giver-of-life" way, but it's simply not true. If lightwell is somehow saving this one person, you're probably better off using that cast time to drop a renew on him instead. That way he could be actually doing his job in the raid rather than clicking an object to save his life. Beyond that, due to the breaking nature, if a lightwell renew is going to be saving his life, it is probably going to be broken by the damage and that guy is dead anyway and it's your fault.

I have been a dpser in raids and I will click on the lightwell if I need it (and as my dpser is a warlock it is fantastic), but if we're to be completely honest, non-warlock dpsers find it to be a complete pain in the ass, and are mostly doing it because dpsers live in constant fear of getting on some kind of healer blacklist if they offend you.

The lightwell debate is difficult because its usage is impossible to model from raid to raid and fight to fight. However, I can speak for myself as a healer and say that I'm uncomfortable delegating my healing role onto other people, and maybe i'm a control freak but I like to be the one actively making sure that my healing assignments get healed.

I agree with that 100%. BUT I wasnt saying it should be used as a primary means of keeping people alive. Its definatly a supplemental asset and should be used as such. This is why said used intelligently. Expecting dps to think that they may be partially responsible for keeping themselves alive is completly unreasonable. If they didnt pop a health stone or pot I tell them to stop complaining about heals. We try to use an attitude of personal responsibility. Obviously its the healers responsibility to keep people alive. However at the level of content and progression most of us aim for, if your DPS cant make an attempt to keep themselves alive that too is also a problem. Train them to use the shiny lightwell :P
.

Although I completely agree with Isen about being nervous in regards to delegating your role as a healer to the raid group, things like health stones, health potions, and bandages are all ways the raid group can self heal. They allow us to focus on primary targets, and save our GCDs for more important purposes. Health stones used during encapsulate or while burning on KJ greatly improve survival rate due to reaction speed alone. Every healer, at some point has to decide between two dying targets. Therefor self healing can be a vital part of the game.

If, at the end of a raid, SWS has lightwell doing a better job than another point could have, then it becomes usable. It's the sheer lack of use and rarity of viability that makes it something I always pass on.

On a sidenote: The lightwell discussion has already been elaborated extensively in the Priest WotlK Preview Thread, coming up with the same discussion right here is quite pointless when a simple thread search provides the same results.

Are these stat weights good ones:

Haste 0.4500
Int (crit) 0.0361
Int (mana) 0.2295
Int (regen) 0.2133
Int (replen) 0.1753
Int (sf) 0.0825
Spellpower 0.6000
Spirit (regen) 0.3879

And in summary:
Deep Holy Priest Stat Weights:
Spellpower: 0.60

Intellect: 0.74
Crit: 0.10
Haste: 0.45
MP5: 1.00

What would you change? And why?

It kind of bothers me that people are saying that you get a SoL proc on almost every CoH, it's simply not true. Very easy to show with some simple math.
20% crit rate at level 70: 0.9^5 = 59% chance to not get a SoL proc.
Even at 25% crit with the glyph at 80 it's hardly going to be on every cast: 0.875^6 = 45% chance to not get a sol proc. The only reason you say that is that when you use it you normaly spam it a couple of times, once you cast it four or more times in rapid succession do you start reaching the almost every time stage.

Anecdotal evidence is not meant to be taken as actual evidence, and I'm sorry you mistook it as such. I was illustrating the relative frequency of occurrence of events between two different cast styles, COH vs. geal spam. My intent wasn't to provide cold hard data, it was to show that modeling SOL vs. lightwell is a near impossible and situation-variant task that makes it not worth the time. Further, I didn't think such a model would actually convince anyone of anything, since the mechanics modify playstyle, not throughput and thus don't respond well to modeling the same as spirit / int conversions (for example). Further, I view the endless arguments about SOL and lightwell as (nearly) pointless, because the choice between the two isn't the only choice out there, you can sacrifice throughput spells instead, so taking the narrow view of SOL vs. lightwell seemed to be choking this thread, and perhaps my response was a passive aggressive response to try and end it.

edit: the argument between SOL and lightwell isn't pointless, I just feel that at this point new posts in the same vein aren't adding anything to the discussion, this one included.

Have you done any research into the impact of the new regen mechanics combine with the [Darkmoon Card: Blue Dragon], or [Bangle of Endless Blessings]? I heard roomers they scaled down the bangle as your level increases but I haven't heard anything about the blue dragon.

I'm well aware of that, and it wasn't really directed at you and your post only. My point is, you won't be getting a SoL proc every time you cast a CoH. I mainly posted the numbers to show that SoLs value is going to become diminished with CoH on a 6 sec cooldown.

Your first statement is correct, but the second is not really true. In WOTLK, the coefficient on int/spirit regen will drop dramatically as we level, and consequently we will get much less spirit based regen at 80. From a tester thread on the beta:

WotLK Beta (US-English) Forums -> Please do something about priest mana regen..

The coefficient on spirit regen will drop to about 60% of its effectiveness at 80 compared to what it was at 70. Priests will be much more reliant on Max mana based regen mechanics, such as shadowfiend, mana tide totem, and replenishment than on their personal int/spirit based regen in comparison to before. The Darkmoon card will still be 2% of your spirit based regen, but that overall spirit based regen will actually be lower at 80 than at 70 given comparable stats, and you are probably much better off going with a different type of trinket.

This is one of the reasons that const and dwarfpriest and all are weighing spirit so low in comparison to other stats. It is an ok stat for holy priests because of its synergy with other talents, but it is weak now in terms of its contribution to mana regen.

I started looking at the [Darkmoon Card: Greatness] as an alternative. However I am not sure spirit will be my top stat so proccing 300 spirit and then trying to cheat the 5sr, might not be possible.

You can proc 300 intellect though. Interestingly enough, its theoretically possible for this trinket to be 90 spirit / 300 intellect proc or 90 intellect / 300 spirit proc.

Seems like it'd be a good pick, with the Spirit proc being viable for Holy. But to your point, you can wait for a 300 intellect proc and then hit your shadowfiend.

Crosshairs, do you know if the +90 agility is there for sure or is it +90 to a stat of your choosing then procs your highest stat? One way or another as a priest it should proc either intellect or spirit both of which increase our regen.

It is good that they are weighing spirit low. A Disc priest sees very little use from spirit, as they should have a high if not 100% I5SR casting time. They gain a bonus 5% from enlightenment and only gain spirit form regen from it. As a Holy priest there are more ways to cheat the rule (via free spells) as well as a direct conversion to spell power. However, for both Holy and Discipline, intellect provides us with more opportunities to gain benefits from each point. The top end mana increase, as stated above, increases our shadow fiend, replenishment, and mana tide totem (as well as starting with 20k mana will be super!). Not only that but with a direct conversion to crit strike and also increasing our passive regen it seems to just be better in a 1 vs. 1 situation. Discipline priests also must love the +15% bonus from mental strength.

Liths, this is the last thing I want to comment on. I think your math is a bit off. You would need to use a probability equation (Binomial Distribution, I believe) to determine the chances that you would have to get a crit first, then check that chance vs. Surge of Light.

If you had a 20% crit chance with a glyphed CoH (6 targets) you would be looking at six chances to get a crit (SoL proc), each individual in themselves.

I'm still having a tough time figuring out the correct model to use. (Havoc any suggestions?)

The original post may be correct. The implication is that there is a half chance on each crit, the chance of each NON-proc is (1 - C/2), where C is the crit chance.

Chance of a proc, on a single hit:

Chance of a single non-proc:

Chance of n non-procs:

And that looks the same as the implied calculations above.
