Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - Enhanced Edition Oath and Power Stance Broken?

I like power/defense stances (and other stances, except the one that return back damage).

I use them for
guerilla-sniping on my rangers (marksman offensive stance).
buffing armor or movespeed on my mages (man-at-arms stances).
buffing backstab damage (and movespeed) on my scoundrels (man at arms offensive stance).
improving armor on my tank at the end of his turn, if needed.
