If the robes aren't gonna get restricted to monks and spellcasters in the future, it'd be pretty amusing (and a little disheartening, perhaps) to see min-maxy Dexterity + Constitution barbarians wearing expensive silks all caked in blood and mud along with a shield and a scimitar or something.
Is that a thing? Barbarians fencing in robes?
Using finesse weapons under rage seems like a Monty Python scene.
