Warrior, and a little bit Monk. This two tanks fit me most of all. Their mobility is so awesome, and their brand new active mitigation system is so cool to master.
Obviosly hate tanking with pala and dk, it is so idiotically simple and facerolling compared to warr/monk.
Never tried a bear, because in general I hate druids' gameplay in any spec. As for me, any druid spec in general is a bad copy of another class spec (bear - bad warr, cat - bad rogue, resto - bad priest, etc, etc).
And, by the way, loved draintanking with my aff warlock back in BC, lol. And would love to see a new clothie tank class - disc priest. Instead of doing shitty, unbalanced and in general idiotic absorb-based "healing", it'd better be a smite/pw:s oriented badass tank, oh dreams.
