Sylvari necromancer. I'll probably be in the human starting area though cause I like it so much.
I personally really hate the human race/starting area.
So I don't plan to ever be there, I'll probably just recreate the norn ranger that I've been playing with.
I'll probably also make a charr warrior at some point, because warrior seemed pretty fun.
Also an elementalist that will probably be an asura or sylvari, depending on what I think about them when they get added.
And engineer wasn't to bad.
I didn't really like the necromancer or mesmer, haven't tried guardian or thief, because I hated paladins in wow and have never had fun being a stealthy class type in any mmo I've played.
