Possible 'official' hint to the role of the new jobs added in 6.0?

Taken a moment to think about how very uninspired that sounds compared to say a Compass mage that takes advantage of positionals to inspire fortune and harmony in the party. A healer with a gun is too far out of left field. Maybe some other weapon, but I doubt a gun wielding healer.

Geomancer isn't a 'compass mage', it uses bells/incensors and works by attuning to the aether of the earth below them, and uses earth/wind/water element spells. It has established lore via the Four Lords questline and the Swallows Compass.
It's too similar to WHM just without the level 61+ light magic.

It would probably work best as a caster DPS, as it could capitalise on the WHM elements unlike any other caster DPS, and use things like channelled spells and ground effects.

Chemist could have a mix mechanic and open up total freedom over the healer modalities, breaking down the shield/regen dichotomy.
