Tanks , and the dps roles are fine. Im saying this for the healers bacause SE has limited the healing class to pretty much ONLY HEALING. every healing class has what is essentially a reskinned, carbon copy of the same 3 skills, and really it seems to be all they need.

Changing the HEALER title to SUPPORT does NOT change the classes themselves, only HOW they are defined. I.e the healers would be defined by more than just their healing, and would open up the next "Healer" to work in a totally different way. Hek, with the SUPPORT title, the next healer would be able to be something that has no direct heal at all, but through other abilities would be able to support and keep the party alive.
