The next caster

[JowyAtreides]

I hope they add Magician or a class like Ace from FF Type 0. Most of the other casters outside of rune fencer( would be too close to redmage) are either more tanky or they fall under more of a healer aspect.

I wonder if the next dps job will be a caster, melee or ranged physical.

Probably Berserker, dual wield hand axes.

As for caster, the only ones I can see, are Geomancer (the more likely class to be introduced as it has been referenced and if images I've seen in the past are real, would wield hammers) or Elementalist (probably too close to RDM/BLM).
