Yes, I am so happy that spam healing is no longer a tactic, down from the most viable tactic. No more crappy healers spamming a heals with a full mana bar. I can't wait to see the effect, assuming it is the desired effect, namely healers have to play with their heads instead of the spam macro. No more discos, holy palas or resto druids running around spamming instants on everyone, at full health or not, and call it "skill".
I am also aware that it's gonna affect PVE, but then, it is the best way to separate good from bad, and not just healers, but idiots who just don't move out of the fire, frost or whatever.
My fiance, a holy paladin too who is a terrible pvp-er can keep me and several others alive while having 2-3 dps on her all the time. She clicks those spells like a pro. Guess not in two weeks.
I saw several threads about healers quitting because they just can't handle the new requirements, the spamming stops... awww, no more mana, got to learn to play, nah reroll warrior...
This is a good expansion, I like it.
