I honestly don't see the problem.

Is tanking any less fun because of these changes? Nothing has really changed for Paladin, and Warrior now has more buffs to keep an eye on and more combos to commit to muscle memory. If your DPS/Healer roles had learnt to pay attention to their enmity meter in 2.0 you never had any threat issues then - now they can open up a bit more without having to baby the tank's threat generation as much.

Basically; "I dislike the new synergy and pacing of combat because certain meta-game aspects required everyone to sit and watch a meter to pace themselves off my threat generation and now they don't need to watch that meter as much because I can generate threat more quickly than before." To which I just don't really have anything to say but.. uh sorry I guess? :/
