Warriors do have to manage rage they pool it then cs and spam slam. They also have to worry about positioning in random battlegrounds because if you just run into a group fight as a melee with no heals you are dead. I would say hunter because they can shoot in melee range but can't be kited like a melee. Everything they do is instant as well. That and you can just sit in the back of the herd while doing max dps and won't have to worry about being stuck in 200 million instant aoe cc.
