Wearing chain and light plate - aka light armor - is not enough to make a caster a tank. Also, making a quick comparison to FFXIV, where DRGs wear light armor and are squishy, tell me, how would a tank job, geared with similar equips to a DRG, survive a tankbuster? And if I remember right, Red Mages always had lower HP growth than a White Mage (since FFI).

I'm sure the devs COULD make Red Mage a tank, but just like FFXI did, by completely breaking apart from the Red Mage archetype and making a Mystic Knight by any other name.
