(Of course, just as with the other three roles they currently use, there should ideally be multiple different classes that take different approaches to fulfilling the support role.)
Actually, healing is not a role, as it's a subset of support, since the healer supports the group by keeping people alive. This conversation is more about having dedicated buffing and debuffing classes, like FFXI's bard and red mage. The design team could definitely create those classes and a formal requirement for them, but as mentioned, that would create another choke point for queues, and since the class is now required, you'd have to balance around their presence, so you'd in effect be weakening every other class for the sake of having those classes present. Also, organized groups would strive to find way to reduce their impact, so it'd collapse back into heals, damage, and tanks. The current design of spreading buffs, debuffs, and CC among the various classes and job is probably the efficient to balance the game.
