Instead of removing unique, they should just rework the glamour system. Like a own glamour gearslots, where you can add the glamour to the gearset (will still cost prisma) and don't need to put it on the gear.
Or bring out 2-3 sets of same ilevels, so every job who share gear with other jobs can have their own set.
