geomancer and ffxiv story elements

We already got enough magical healers for now, I'd like something different then a magical healer, I'd like a more non magical based healer like a field medic or chemist or some kind of combat doctor.

The problem is the immediacy of combat here. In a turn-based RPG you can assume your combat medic is doing stuff between turns. In a live-action battle... what do they do? How do they instantly apply HP restoration in a convincing way, outside of throwing potions?

Magical healers are much easier to make sense in battle. That's why we have a focus on them.
