Currently I've got a level 15 or so bloodletter. There's only a few classes, but each class has a few different skill trees that change the way it's played. I can also one shot almost every mob other than the dungeon bosses, who put up a mild fight at best. It's easy as crap, but still fills the void until Diablo 3 comes out. Hopefully I can get the money to get a key for it, so I can play on launch.
