i was originally going to go with the jew class, but have ultimately decided to go with the mage.
i prefer casters however i hope they dont work like the enemies do in the sense that you have to position yourself behind your party because your super squishy (probably not the case).
I'm going mage both because it intrudes on Cartman's "Grand Wizard" turf and I really want to see how they LARP all the spells.
