Asura are definitely sorely lacking in options for faces and hair. There’s only one option for an attractive (for lack of a better word) face and hair option. Sylvari could definitely use more of both as well. I understand that these were the last two races completed so I hope it was just a matter of running out of time and they will implement more.
I find adequate hair options is the most effective way to help your character stand out. Of all the things you change or tweak, the hair is the most obvious (given you aren’t wearing a helmet).
Just want to add that I absolutely LOVE this game and this is a small gripe among all the praise this game is due.
