For me personally, I just flat out never like the male models of any races in any RPG game, especially MMO's. I dislike bulkiness (AKA Buffed characters ect) and usually I never like the animations of male characters. When it comes down to aesthetics I just simply always prefer female models.
That and I seriously just prefer looking at a female over a male if I'm gunna be playing for long hours at a time(It's actually almost like an OCD for me, I played my friends character the other week to raid for him while he was on vacation, I literally couldn't wait to log off just because his character was a human male). That and I guess knowing my characters armor/casting animations ect ain't what I like just drives me nuts.
