The MP drain of fist stances is too large, it needs to be reduced. Even using sucker punch, and featherfoot while soloing, it's still drains your whole mp pool within 2 minutes.

And what about boss fights where you have no way of naturally recovering mp? Depend on Sucker punch? I don't think so. Not to mention that using sucker punch to recover a little mp for your fist stance means locking yourself out of the Demolish -> Howling Fist combo which is a significant amount of damage over sucker punch.

The mp drain needs to be revised so that it can be decently sustained by sucker punch, I don't care if the drain eventually outlasts sucker punch, but right now it drains way too fast.
