Human for me, I am human, I want to take sometime out of being a human when i log onto wow, I don't have anything against Humans as a race in WoW, it's just not the kind of race I want to play when indulging in my fantasy game.
Humans and Orcs are, by far, the least interesting of all the races. Their animations and models are garbage. Hell, half the time, human and orc arms look like they're attached to the torso by a handful of Silly Putty any time they raise them above shoulder-level.
