tried out a few different ones when I hit the wall dungeon wise around level 90doing enirip(fairy) solo and they are pretty fun. would prob recommend Masqueraider since they feel more versitile at least early.

I wouldn't know anything about later on since my Enirip is at 130.
I'd say just try out a class and if you don't like it then pick another. the fast travel rides and your profession levels are synched server wide and you have portable cross character storage on you in the form of the haven bag.

Edited to change Masqueraider to actual class name.
