The problem is, Gary Gygax's spirit lingers among even FFXIV with the 'no heavy plate armour on mages that would otherwise interfere with their ability to concentrate' and 'healers forbidden to wield edged weaponry that might draw blood' concepts from DnD remaining very much in effect here (hell, they were in FFXI too and specifically stated as such in the game's manual).

So sadly I don't see SE changing this at all.
