Tbh it's better than china's in a lot of ways. The main way people get the skillbroken skills is the potions not the books themselves. And those are very rare, except the really weak ones which you can build through a almost rich field like thing. In china skillbooks is luck based entirely, and in most cases it's stacked against you. At least this way it's 100% f2p, cause you can't money magic you sausuke frags. IMO, this can be better if done right, like costing a bit less frags. Otherwise it's gonna be p2w like it, for the most part, seems to be in china.
