Charr are ugly. That is all.
I lied.
Charr are EXTREMELY damn ugly.
Asura are awesome but I don't think people should try to emulate their character type just because they are playing one. With the 'Morality' system in the game (ferocity and all that jazz) you could make a loving and caring asura. Why do people think that just because the majority act like they are high and mighty, they must all be branded by the same label? Hell, if you did that for human beings, you'd find that we'd mostly be selfish assholes, not much better than the asura.
I'm just.... saiyan.
*tumbleweed*
I'd say that the Norn are the most realistic with their goals and values, Humans females are too ditsy and human males are 'Generic hero type A'. Sylvari are a kind of strange mix, I'm looking forward to seeing how their personalities shape up, I just hope we don't see a repeat of the LOLBOOBS night elf syndrome.
