If there's one thing that this game is lacking, it's surely not class variety.
Hell, you can be an archer that shoots magic arrows instead of real ones.
+ how you can min/max characters, or mix any classes you want for yourself. But unfortunally your pawn cannot be all classes. But in the end, it realy doesnt matter to much.. even if you totally messed up your character.
One tip tho. The only thing that has been bugging me. You can only have 1 progression. meaning the moment you hit New Game, your previous character and pawn is lost, unless you fiddle around with the savegame file, and swap them around.
