I'll use the MMO-champion calculator. To start with;
Priest (Forums / Cataclysm Talent Calculator / Beta Skills/Talents)
-Binding Heal base healing value increased by 20%, from [ 3960 - 5091 ] to [ 4752 - 6110 ]
-Greater Heal base healing value increased by 20%, from [ 6968 - 8098 ] to [ 8361 - 9717 ]
-Heal base healing value increased by 20%, from [ 2613 - 3037 ] to [ 3136 - 3644 ]
-Flash Heal base healing value increased by 20%, from [ 5227 - 6074 ] to [ 6272 - 7289 ]
This is awesome because I was already coping pretty much fine in heroics and am now downright 20% more effective.
As for specs; I'm currently rolling with these two
. The disc one is pretty much what Horsemouth mentioned, except that I don't care for haste as you all know. The holy build is basically the normal level 85 one, but since I can't grab Archangel yet anyway I figured that instead of three more points in disc I'd just grab Test of Faith. My glyphs are constantly switched around now that I can, flipping that one slot between Mass Dispel, Holy Nova and Smite.
For Cataclysm, it currently looks like these will be our options: Disc
, picking up nearly half the disc tree to allow for Smite-healing or Heal-healing depending on what the situation is like. Probably my pick fo disc.
-Disc jack-of-all variation 2
, the same thing but with Desperate Prayer instead of Power Infusion.
-Disc jack-of-all variation 3
, disc for the OOM (or newbie) priest. No Surge of Light sucks, but you'll have an easier time keeping your mana up, as well as with managing aggro.
, with 3 points that can go in Inner Sanctum, Deperate Prayer, Surge of Light, Empowered Healing, Darkness or Veiled Shadows, as seen fit. Whether this will be completely viable for raids remains to be seen, but I'll be damned if there won't be at least a small group of followers for it.
, with one point for Desperate Prayer, Mental Agility, Darkness or Veiled Shadows. I predict this is going to fail, though. Smite and Heal currently overlap to an extend, but while Heal could replace Smite in most cases to make Smiteless Disc an option, I don't think Smite can replace Heal. I could be wrong though, people will need to experiment with this. Holy
with Archangel. Fairly standard.
-Holy jack-of-all variation 2
; less AoE heal, more tank heal. Bit more 5-man focused because of that.
-Holy jack-of-all variation 3
, featuring sir Speedalot. This is probably what I'm going to go for in my holy build.
. No Archangel but Veiled Shadows to make up for that. Grabs really everything you want in the holy tree and adds some rough throughput. A solid build in its own right, with all the gimmicks there.
. Assuming no Smite ends up being a viable option, this is what you'll see the min/maxers walk around with. All throughput and no play, avoiding all gimmicks and playthings in the holy tree just to get that extra % healing. Can possibly drop a point in Serendipity to pick up a point in Blessed Resilience.
On another note, I need to re-evaluate haste. Even though healing has been made less 'spammy' in Cata, you'll probably still spend 99% of your time casting.
The way healing works right now is that you're in a situation where everybody in the raid/group drops to around 70%, and you attempt to heal through any damage you can by just using Heal and Penance. If you stop healing for 5 seconds (or if someone stands in the fire, if the boss casts a big punch at the tank, etc), it's not that somebody will immediatly die, but instead the entire group will now be balanced around 50%. Another 5 seconds brings you down to 30%, at which one small error at their side (being slow on the fire) will kill them. That's where the rest of your heals come in - you'll need to use less efficient heals like Flash Heal to bring that balance back to at least 80%, and this will cost you in terms of mana.
While you still won't "need" haste as much as you won't "need" crit, ironically enough, haste seems to have done the opposite of what seemed logical to me and has become more valuable after all - if you have a lot of haste, you can get away with using Heal/Penance to heal up more severe damage, allowing you to cast less Flash Heals and thus save mana.
