On this particular point, you might be confusing gear and glamour. Yes, most of us would want our different jobs to look different, but that’s about using glamours - otherwise you’d have to deliberately equip weaker gear to some classes just to make them “different”! (Which you still *might* do at max level for jobs you don’t care about so much, or two jobs at similar levels sharing gear, but generally there’d be no point to it while you’re leveling up.)
