There are number of fun classes, but the one I enjoy the most is the the Arithmetician. As a statistician, this class immediately appeals to me from the numbers side. While slow in speed, the ability to kill everything, revive/heal your squad or inflict status ailments en masse is just cool. In the end it is more suited to a second ability because of the speed factor, but it becomes even more devastating the higher powered spells you learn. Not really sure why every sentence before this one starts with an objective phrase... #NotHowToWriteWell.
