Red Mage use Casting gear!!

[Vexander]

SCHs and MCHs have had to deal with shared gearsets that don't fit their aesthetic, so don't see why RDM will/should be different. All SE has to do is diversify future gearsets so that it's not always catered to one Caster aesthetic (which they currently do anyway).

A good point. Seems each expansion has an, 'Artifact,' set which is based on the individual class, and then the sets are designed around a theme, such as raid gear being designed to the raid, or tomestone gear being designed to what sometimes seems to be a random theme, like Primals out of nowhere.
