We might be looking at everything all wrong. Maybe its not tank/dps/healer.

In HW we got three jobs right? (Not counting Ninja, it was more a late delivered 2.X job.) DRK is a tank, AST a healer, and Machinist a dps. But maybe we misunderstood. Machinist was a Ranged dsp. Maybe we aren't getting the 3 roles, maybe we are only getting the only sub-rolls untouched, melee dps (Dancer), and Magic dps (Red Mage).
