The basic premise is for soloing... either bard or ninja subs would lower elemental resistence thereby increasing damage outputs.

Plus, dual wielding clubs with INT, MND, and whatever would further bump that number.

I was looking at blackmage and redmage, but their increase come late in the game.
(I'm only lvl 16).

Is this a good enough reason to try geo/nin? or should I just stick with the geo/rdm or geo/scholar?
