Healing in WotLK
Which spells are we going to use in WotLK? What will be my main spell? What will be the difference between raids and other dungeons?
Ghostcrawler (a Blizzard Developer) wrote an interesting note on the beta forums:
In our minds, your go-to spells when healing anything bigger than a 5-player group are Rejuv, Regrowth and Lifebloom. You are probably not benefiting your raid the most if you are chaining Healing Touch on the tank while the paladin is trying to keep everyone up with Beacon of Light.
Healing Touch, Swiftmend and Wild Growth are all very useful spells. But they are intended to be used in smaller group or when something unusual happens in a raid. If the entire group takes a lot of damage at once, that’s a good time for Wild Growth. If a melee dps class is very wounded and you don’t have time for the bloom and Swiftmend is on cooldown, go for the Healing Touch.
If any class is the “fill in the gap” healer, it’s the Holy priest. Their strength is in versatility — they have single-target heals, group heals, instant heals and hots. The standard (but by no means only) way to heal a raid is to have a Holy paladin on the tank along with a Resto druid, have a Resto shammy AE heal the group, and then put the Holy priest wherever you need them. We are also trying to get the Disc priest into a role similar to the paladin, but based more around damage avoidance than efficient, quick heals.
Nourish is supposed to be a Flash Heal — fast but expensive. It may be too fine a line for a class that already has Swiftmend and a (much improved) Regrowth.
