Next healer class released should be

[Katnille]

At the risk of ridicule, I think the next healer down the road is Geomancer. The game hints at the job in several places. The Astrologian quests, the dungeon "The Swallow's Compass", and the Peacock mount they recently introduced. I'm sure there are other subtle hints I'm not pointing out, like Gosetsu and other subtle nods. Considering FFXIV's take on Geomancers being Healers, I deduce that if a new healing job were to be developed, I'd stake my bet on GEO.

I totally agree!
