I mean lets be honest, its already "weird" that you can swap out a mastery for a bow and get a mastery with the longsword after a day of adjustment. We accept that this is just an "awesomeness factor" of being a badass fantasy fighter.My point was that unarmed Strikes should not be something you could practice and swap masteries as easily as a sword.
So under that scope, acquiring unarmed mastery is just as crazy (and therefore, not crazy at all).
