I would accept limited Barrelmancy if some of the barrels were Mimics. Random selection. If you put one in your pack it gets an automatic Grapple, surprise and Critical Hit on you!
I'd laugh so hard if Larian adds in barrel mimics later in the game. It'd be a nice meme for Larian.
I'm still in the camp of throwing barrels bad, throwing oil flasks good. So if we're looking for limited barrelmancy, oil flasks fit the bill.
