Geomancer (CNJ Job) concept

[Viviza]

The summon spells DO change the fundamentals. Pets are at the core of the arcanist, and they work differently for each job. Summoners simply follow the arcanist with attack and tanking pets, much like how white mages take all the conjurer abilities as is. But scholars make a departure with core abilities (again, the summons) remapped towards healing.

Conjurers could easily follow the same pattern, but reversed from how arcanists did it. A DPS offshoot like geomancer just needs to swap a couple of the more potent heals away into something else much like how arcanists had their single best DPS tool (the pet) changed. Summoners work perfectly fine with low level healing abilities intact. A geomancer with a similar kit isn't going to break anything.

I'm not saying that they WILL do these things, but they could, and it wouldn't be a radical departure from what's already there.
