Next healer class released should be

[MirronTulaxia]

Honestly, I don't see room for another healer in the game. Square Enix hasn't had a lot of success with our current three healers. A fourth one would make it even more difficult to please players.

I feel like they kind of need to figure it out then. Every other role of the five roles has had something more recently than Heavensward. Healer is due for one.
