You cannot equip the very same item to more than 1 gear set.

Gear sets don't seem to be favoring gear swapping at all. Hopefully we'll remain unable to switch gear when in active mode, and thus especially with the faster paced battle system gear swapping will become very much not worth it.
Yea I am petty sure gear sets are just a way to switch gear fast when changing jobs and you still won't change gear a bunch while in combat. This isn't FFXI and in FFXI if you didn't use spellcast it put you at a disadvantage, the whole gear swapping thing was kind of an accident by SEs part in that game.
