I’m on board with a GEO, healer would be neat, I’d love to see it manipulate weather and terrain even it’s just a simple Aura like in FFXI and their Loupins. Stuff happens within that bubble. I made a small concept a while back where it uses weather patterns to disrupt the terrain and hinder foes / help, heal, buff allies.

But I have a feeling maybe SE may add them in 5.5 and surprise us! #wishfulthinking
