I'll provide some dissent here. As an Idris geo, the set-ups were quite specific to the point of being really biased. 2 Geos were often needed on some of the end tier mob to guarantee vex/attune; always.
I would argue requiring a geo vex/attune for every fight seemed really weird to me. And it's not like Bards suddenly can do these things. Geos remain the only job that can provide vex/attune
and frailty is not nerfed.
I think they can still tweak the mobs m.eva and /m.acc down more to appease people however. Change is never easy. It should also be made clear that Geo hasn't lost their position in the party, though dual Geos maybe less desirable now, so the job warz stuff that keeps cropping up seems meaningless.
I'm more concerned they make sure people can still easily clear the high end content that they very clearly designed with the bugged Geo magic bubbles in mind but it appears they haven't adjusted the mob values sufficiently to account for the reduction in the geo magic bubble's potency. That to me hasn't been made clear yet.
