Both the Spellweave and Moonshroud gloves are pretty mediocre, but if you're set on making one, make whichever is cheaper. The hardest part of early heroics was mana, but I'm not sure how that will fare for you with a disc spec. And no, imp DS is not worth the two points.

The primary argument against imp DS is the fact that it doesnt stack with totems, right? Or there are more reasons against this talent so that its not worth it for heroics?

Yes, that's the primary reason not to take it.

It's going away in 3.1 anyway.

It's a good talent for heroic healing. 100 extra spellpower is a nice boost if you have around 1300(which is where most people are when they get to level 80 if I remember right). In raids it's pretty much useless since it doesn't stack with totems. When you get raidgear you won't have any problems healing heroics anyway, so better skip it for something better.

Moved. Sorry

Pardon my ignorance, but what is the rough expected uptime of Inspiration when a Holy Priest and/or a Disc Priest are on a tank when they are assigned to heal them or directions on where to find such information.

Same formula for all procs : uptime = 1 - (1 - proc_rate) ^ proc_occasion

In your case, it leads to Inspiration = 1 - (1 - c1)^n1 (1 - c2)^n2,

where c1 anc c2 are your both critical rates, and n1 and n2 the number of heals (that can proc inspiration) you cast on the tank in 15 seconds. Note that penance counts as 3 heals (each tick can crit and trigger inspiration).

Yes but I'm more interested in help modeling the spells used by those priests and how that affects uptime. For instance, I'm am uttterly confused about what these two different crit rates you mention are.

What's there to be confused about?

You mentioned 2 variables - The disc priest and the Holy priest; thus, he modelled the equation to include both priests instead of one.

Inspiration = 1 - (1 - c)^n

Is the equation for 1 Priest. So let's remove the holy priest and say you've only got a Discipline priest on the target. The inspiration uptime is then as the equation above. c is the critical strike chance of your discipline priest and n is the number of heals you can cast in 15 seconds.

Now if we factor in the Holy priest as well, it changes the equation a bit to add in the chances of having inspiration proc off the second priest as well.

Inspiration = 1 - (1 - c1)^n1 (1 - c2)^n2

c1 is the crit chance of your disc priest, n1 is the number of heals your disc priest casts in 15 seconds (duration of Inspiration)

c2 is the crit chance of your holy priest, n2 is the number of heals you holy priest casts in 15 seconds

Speaking without math in mind, if you have a disc priest on a tank, you will usually see around 100% uptime of inspiration - depending on whether they spam a bit more or lay off - just from experience, I raid as Discipline with about 30% crit raid buffed (maybe a bit more). With one penance I almost always get a crit on at least one tick of it, even though I've been holding it back on encounters like Sarth where I want to have it off cd (usually after a breath during shadron+vesp) I still find myself casting it around every 15 seconds or so. Other than that I am casting flash heals, which are about 1.28-1.3 second casts, and considering my crit rate, about every 3rd one crits (though in practice it isn't like that, sometimes I will go a bit without a crit, sometimes I go with the nice 3 or 4 crits in a row).

I've rambled a bit, but speaking from playstyle - I think holy is going to have a bit lower uptime percentage than disc due to Holy not being as spammy as disc - and in 3.1 both specs are going to be less spammy due to necessity, with mana becoming an issue, just spamming heals will not always be a smart or efficient decision.

As I said I do not know the spells of choice for either a holy or disc priest on tank healing duty and what portion of those spells can trigger inspiration.

Holy heals tank using POM on cd, and gh spam. POM doesn't triggers inspiration (at least on tooltip). So, without any haste and not taking IHC into account, it's just one gh every 2.5 s. n=6 is a reasonnable assumption for holys (POM will be balanced by haste and IHC).

Disc heals using penance (one every 10s let's say, 3 ticks), PW:S (not triggering inspiration, and anyway, crit rate is low for the glyph), and let's say flash heal (gh while Borrowed time, but that's leads to one flash cast time anyway), and POM.
For a harsh modelization, in 15s :
- 1 PW:S 1.5s
- 1.5 penance, 4,5 heals, 3s.
- 1.5 POM, 2.25 s

This leaves to 8.25s free for flash, which is around 5 flashs.
So you have finally n=8.

At 30% crit for both, you get inspiration = 1 - 0.7^14 ~ 1

That's assuming that your priests are spamming on the tanks, and that they heals about the way I do. But one disc priest can manage around 95% uptime anyway, when spamming flash, penance, PW:S and POM.

Question: What is hit cap for a non-shadow specced dps priest (sounds better than lolsmite) Also, if one could point out or PM me a useful well of knowledge of such a spec that would be much appreciated. (I dislike shadow and figured give it a whirl with dual-spec coming out)

Edit: Also, PoM crits also trigger Divine Aegis

This is from the second post in this very thread, but:

Combat Ratings at level 80:

1% crit = 45.9 critical strike rating
1% hit = 26.23 hit rating
1% haste = 32.79 haste rating

1% crit = 166.67 intellect

For shadow priests with 3/3 Shadow Focus and 3/3 Misery, you need 11% hit, or 289 hit rating to be hit capped at level 80.

So for a build without shadow focus or misery, you'll need the full 17% hit, or 446 hit.

Is there any math backing up the chaotic skyflare (21 crit rating and 3% crit bonus) meta over the ember skyflare (25 spellpower and 2% int) meta for shadow priests?

Until the patch a large majority of your damage comes from abilities that can't crit, and you free up two lame purple spell/spirit gems for more pure spellpower gems, as well as getting a minor amount of int (and thus crit). Does it actually effect the damage modifier on dots from shadowform or something?

With the upcoming nerf to spirit regen in 3.1 which DC:Greatness card would be better, the spirit one or the intel one? (assume I would have replenishment guaranteed for the sake of argument)

I don't know whether or not you actually understand the spirit regen changes, but the in combat mana gained via spirit has not changed ( due to meditation/intensity buffs ) so it will only effect the times when you manage to go outside the five second rule.

The 90 Int Greatness trinket has always been superior in terms of just pure mana regen, the OO5SR nerf to spirit regen does not change this.

If you manage to have your buffed spirit higher then your buffed Int to allow a 300 spirit proc from the deck, the best possible scenario with the Greatness deck trinket would be attained.

How does fade work? I've seen about 10 different opinions on it, which one is up to date?

Here's a link to the spell ability on wowhead:

Fade - Spell - World of Warcraft

As the ability description implies, it reduces your threat to all targets (Apply Aura: Mod Total Threat (Fade)
Value: -90000000) a large amount for the duration of the effect. The effect does not reduce the threat you generate over its duration, and will remain with you as soon as the -90000000 threat is gone, returning you to whatever threat levels you've generated on your character for all hostile targets who have you on their threat table.

1 short question :

Does the % healing effect of Focused Will stack with the % healing effect of Grace ?

Rationale : Beeing largely the main target in my 2v2 team, I trust the opponent to land multiple crits on me triggering Foccused Will, whereas beeing chain stunned, I don't quite trust myself to be able to stack Grace. If their bonus healing stack I will certainly take both (particularly in 3.1) but until then I'm not sure Grace is worth it.

All effects from your own characters talents stack with each other, but this may not be the case when you start comparing things with other players (for example, other players grace on a target will not affect you). "Do you add or multiply?" is whole another story.

I'm sorry if it was already mentioned, but i missed it:

Does grace healing bonus apply to PW:S?

Is there a GRID addon out there to keep track of my grace stacks around the raid?
