Y'know, I hope that's a monk and not dancer because that would be one pretty cheapass way to mak a class...
also, maybe they just decided to be realistic, unlike the game. 5 a girl won't use the same stance to punch than a boy, morphology and whatsoever
so maybe they took that into account, I mean, the girl stance looks pretty much like the fists of wind (Yeah I know red au ra, just check the stances in game)
in game no matter the race or gender we have the same animation for every classes...

Here are my thoughts on the subjects now if you will excuse me, I need to go back lurking in my shadows. have a good day guys ♥
