There are four talent trees out there that have been previewed by Blizzard. You can check them out here.
So far, three healing classes, and the rogue. And all healing classes seem to be going in the same direction. Do damage so you can heal more.
So am I the only one who feels that if we'll need this little healing in Cataclysm that healers can spend time, cooldown, gearstats (you'll need hit) on dps, that we might just bring in more proper dps and get stuff dead before you get to ever needing healing?
And if this trend develops a bit more will we see a game without healers? In which the only enrage timer you have is your own health and how well you manage to avoid damage?
Or maybe we can just bring 2 healers to a 25man. Have them watch the fight, conserving mana and staying out of trouble, until healing is really needed, release their biggest spells, and sit there regaining mana again?
Either prospect isn't very charming to me...oh well, more of the "I guess we'll see where it's going" right?
