I recommend a bard.
They start off slow, but by the time you hit the mid-late teens, they really start to pick up the pace. It seems like they have something for almost every occasion. They are desirable groupmates. They are great for group pk fights.
If you don't mind empowerment, I think it is a good way to attach yourself to a character. Maybe that initial empowerment kinda sucks, but once you get it, then you tend to stick with the character a bit longer.
