Looks good. Main issue I see is that a lot of people like myself prefer to use Quick Melee instead of stances. It is faster, smoother, and more efficient in many cases, and does not bounce me or the enemies around the map. Specifically, the polearm default melee attack, since it does not interrupt your flow. I wish there was a way to preserve this option. Perhaps a "Quick Melee" stance mod or something that could universally be slotted in to weapons? There are probably better suggestions than that though.
