For one thing, that's' cool yet lame in its own right. There should be SOME advantage to wearing armor over just wearing enchanted clothes. But I really digress.
The problem I had most was that wearing a robe used up two slots. CMON. The whole idea of the robe is to give the mage a distinct look, yet it creates a disadvantage! Why deny the mage, who needs enchanted clothing more than anyone, the one extra clothing slot? I hate it.
Mages should be able to slot as much clothing as a warrior can slot armor. End of story.
Edit - suggestions that I like from below:
- More pants for women (not skirts).
- Shorts?
