Not many pure healers left in the FF lore. But then again Scholar wasn't one and they turned it into a healer so who knows.

Just throwing a few names from jobs we've seen in previous FF, whether they are spin offs or main series.

Potential healing jobs:

Chemist, Bishop, Shaman (Elementalist), Sage, Occultist, Orator, Mystic, Green Mage, Time Mage, Songstress/Singer and Priest/Devout.
