Review Detail of Riq_Fred in HxH: adventure of a lifetime

I understand why many give 1 star; the author made a mistake in the laws of Nen. I'll give an example: is there a Nen user in HxH who doesn't know about the boundaries or oaths that the user can't break? Nothing, even Kurapika, knows that the limitation of one of his Hatsu (Chain Jail) cannot be used other than by members of the Gennei Ryodan; if Kurapika violates the rule, he will die (HxH Episode 47). So in conclusion, there isn't a single Nen user in the entire Hunter X Hunter series who doesn't know a boundary that shouldn't be crossed. Meanwhile, our MC actually violates these limits because he doesn't know, Where is this common sense?
