Honestly there is a glut of DPS ... Another healer and or Tank needs to be introduced.

That being said I also feel a ranged physical DPS would be in order. Crossbows could work for a class. Dual Handguns, could be a class. A thrown weapon class: Boomerang, Chakram, Pinwheel. A slingshot. Or they could go completely unconventional and use that weird tennis racket yoyo weapon Vanile had.
