It would seem that most people on anonymous sites like MMO C and such are in decision that the male human model in WoW is among the worst models in the game. But is this really true? I have honest difficulty in seeing most genders and races in the game, besides Orcs, look as good as a human male in plate armor. Helmets look perfect on them, and are never unusually sized. They have one of the best two handed melee animations in the game, and don't lie, it looks great. People like to complain about their mouths in particular, but if you use a full beard, as you should, it is never a problem.
Of course, it is not perfect. Their run animation is horrid, but that's all I can really think of as horrific.
