Next healer class released should be

[BasicBlake]

We were going to get Chemist in Heavensward, but they couldn't figure out the mechanic properly, and it became AST. Maybe they found a way to impliment it this time.



That is a misconception. GEO is a part of the AST quest, and while the quests do make analogies between the two, GEOs are not healers. They are specifically stated to be protectors. Which could indicate a healer or tank, if implimented. Personally I want the later, since a tank GEO would be more interesting than a healer. But since we got GNB we might have a bit of a wait if that is to ever happen.

I also do not see why this could also not point towards a support caster. Since we we are due for a healer/caster this next expansion. And they are still adding stuff to the game hinting at the class.
