G'raha is all you need. Change him from All-Rounder to Tactical Catboy since he can do all 3.

But if I had to pick 2 others... Sid(DRK trainer), and Gosetsu. Creates a nice character contrast personality wise. The former being a strong-willed vigilante that follows his own sense of justice and the latter being a a seasoned warrior tempered by years of experience in both battle and life granting him wisdom to loosely steer the metaphorical ship.
