What's the formula?

mp lost per ap reset = 4
not 6.

This is cause warriors get 2-4 MP per AP (not 4-6 like on levelup)


I think that's the same for all classes, 2 less MP and 4 less HP per AP compared with SP (obviously for warrior/mages who have skills that add different amounts depending how you gain hp/mp, that complicates it) and you always lose the max out of that range when you reset.
