So I know SE is working toward completely phasing out the class system, so, I thought this would be a cool idea.

I've always thought it was weird that WHM has spells like Aero/Stone or Fluid Aura, but, that's because of CNJ.
If SE is going to make new healers, one based on nature or "life" elements (soil and water grows, wind idk carries seeds in the wind, w/e) would be cool (which is kind of what Conjurer was supposed to be.)
So, I was thinking they could make Aero, Stone, and Fluid Aura "Light based" spells that do the same thing for WHM; such as Dia and Banish.
Then they can freely rework CNJ into a job if they wanted to when they get rid of the class system. They could also call it Geomancer for a nature theme.
