When it comes to character creation I would much rather have hundreds of minute details to make your character origonal. What I hate most about online games is making a character and spending a lot of time on it only to discover there's at least 100 people that look identical. A few ideas:

More Colours, hair and skin

Why can only Elementalists and Necromancers have bright green or blue hair? Equal opportunities please Hm.. I don't know about skin colours, blue skin ftl?

Face-Tastic

Ok think of... the Sims 2. Finely chiselling faces is imo pretty fun.

Though having many small details to chose from can be vitally important for diversifying game-play, others may think it annoyingly time-consuming. And yes I know this cannot be implemented in Guild Wars at this time... but a thought for Guild Wars 2? Ideas and opinions are welcome, but no flames please, had enough of those on the old forums...
