Just vanquishing evil spirits and purifying the land. They call it the foil to Astrologian, painting the contrast of heavenly and earthly energies, but as far as I'm aware there is actually nothing in the game where Geo heals. In the lore they're known for being powerful casters doing things like bringing down airships. I'm not saying its impossible it just does seem to fit when you look at the job as a whole within and without the game's lore."
So if that is the understanding of the class; which I agree with personally, I think geomancer will be a dps class leaving room for chemist healer.
