Well, these are the only ones announced for this month. We'll have to wait and see if get more new classes in the future.

As for whether or not these classes, the Medic seems to have some sort of support spells that involves impaling your allies with a syringe. I think her innate evility allows characters to regain 5% of both HP and SP while inside the base panel. Not sure of the specifics. The Necromancer's innate evility has something to do with resurrecting your foe?
