Of course, I know the story, watched the old anime and such, but still ... I wonder if there is a proper explanation as to why the Genryodan-members are THAT incredibly strong. Is it typical Naruto-esque bullshit a la "well duh...", or is there a real reason? Afaik, they didn´t engage in a nen vow like Kurapika, which *could* explain their strength.

And yes, the whole mafia party is one big disappointment.
