Yoshida did talk awhile back about a 'hybrid' role to take the fourth slot (tank, healer, dps, hybrid), and while he's never spoken positively for a support role, this could be close enough to appease people. Hard to say. Either way, it's liable to create some very interesting classes/jobs ^_^.

Also, earlier someone mentioned Mystic Knight being a tank... and I can't even say how much I'd love that.
