Famitsu interview confirm RDM use INT and share casting gear/SAM share striking gear!

[Alistaire]

RDM wore a few light armor pieces but a majority of their equipment were robes. In FFXI, their main gear was caster gear shared with GEO/BLM/WHM/SCH, while BLU wore more armor that fit with Rogue-like jobs (PUP/THF/DNC/NIN/BST/RNG). I would have bet my life that SAM would share Maiming gear, based on the fact that SAM in FF games usually wore heavy armor or middle weight armor. I know SAM wore light kimonos and stuff in town, but in battle their wore actual armor, so its odd they're on striking and not maiming.

Well, ffxi had all kinds of strange job groupings for different gear sets. There was light cloth stuff that was sam/nin/mnk/pup, there was heavy armor that was war/pld/sam/drk/drg. There was also melee stuff that was rdm/blu/thf/rng etc and then the caster sets that were rdm/whm/blm/smn (and sometimes blu).

Point is, you could make just about any argument you want with ffxi as an example, but we don't need/want ffxi-2.

And in the original Final Fantasy, they could wear more than robes and caster gear. Chain mail and the likes.

And in the original final fantasy there was a piece of gear red mage could wear, but when you upgraded to red wizard, they couldn't. In any case, there's various options for casters to look more heavily armored now, so rdm will be no exception to that.
