No more improved buffs, that is nice, but I wonder if that extends to debuffs, No more having to spend points to get a warrior and druid demo shout to be as good as a paladins would be nice.
We do want to make sure that 10 player raids can get all of the major buffs a little easier. You should feel like most reasonable comps (3 warriors and 7 rogues is not what we'd consider reasonable) give you all of the major buffs and several of the more minor ones. There will be a little more consolidation than what we've described so far.
We are scaling back the magnitude of some of the buffs, as we did with Sunder Armor. We want you to feel awesome when you have strong good synergy, but we don't want the buffs to overwhelm say your gear or skill. We're also planning on getting rid of any talent that buffs a buff. Any buff that is earned solely by talent needs to have a selfish component thrown in so that you don't feel like you should respec if someone else with that buff comes along.
Obviously things like Rebirth can't just be handed to out to more classes unless we did something like a second exhaustion mechanic for battle rez or whatever. For now we're going to try the cooldown at 30 min again. In Icecrown's world of limited attempts, a 30 min cooldown likely meant you just cooled your heels until the cooldown was available again. In Cataclysm the hope is sometimes you'll have the benefit available but not every time, which scales back on how much of a game-changer it is.
