I have tried so many damn times to make more male characters in WoW because I want to get as much content out of the game as possible. However, I can't bring myself to hit "accept," because they're just so UGLY. I find lots of men of varying appearances beautiful or hot in real life. I know boys who are prettier than me. Yet somehow in Azeroth that translates into either 'grandpa' or 'lumpy beast-thing'.
Night elves have their canteloupe arms on weirdly tapering bodies, gnarled faces and hideous facial hair, forsaken males look like frogs, troll male tusks extend so far they look more goofy than fearsome, humans look like cavemen with no wrists, and orcs look like humans except with extra caveman in mossy green. The best you can say of gnomes is you can make them look endearingly funny, and dwarves tend to end up looking like a homicidal Santa Claus. Taurens are inhuman enough to avoid being actively ugly, but it's still essentially a cow, and Belf males look ok if rather irritatingly smug because they're almost identical to females except slightly larger and with a bit more jaw and cheekbone. And even then, looking now their shoulders are so broad their arms don't seem properly attached.
So yeah. I don't mind playing male characters nor do I feel I've ever missed out on an opportunity to play female ones. I can relate across genders, it might even be neat for what roleplaying exists in the game. I'd just like the character I'm staring at for countless hours to not look like a gargoyle.
edit: oops, forgot draenei: they're not quite as bad as humans. their proportions are weird but at least they fit together and their face-tentacle things can be arranged so they don't obscure the face itself, that just leaves the issue of giant ape-hands and the recurring issue of having no wrists.
