Actually I just thought of something. If Nen is energy that gains the properties of mass without being mass itself, why did Razors Nen imbued Dodgeball weigh as much as a bowling ball when Killua picked it up? And before you say "Nen users can allow their Nen to be affected by gravity", I would like to highlight how impractical such an actions would be for an emitter such as Razor. Not only would he have to throw around an extremely substantial weight(remember, while Killua said it weighed as much as a bowling ball, it probably weighed much since it felt that heavy despite his enhanced strength), but he would also have to account for the curve of the ball before he throws it.

So just to recap, Razor's emitted Nen:


 * Contorts like plasma


 * Can be push and be pushed by plasma


 * Carries a substantial amount of energy like plasma


 * Is affected by gravity like plasma

Do you see what I'm getting at here? Razors emitted Nen didn't just have "some of the properties of matter", it had all of them! Every single one! If Razor could make his Nen weightless why wouldn't he? If Razor could stop his Nen from contorting(and in turn transfer more force to the opponent) why wouldn't he? Because it isn't energy. It's matter, which is why Razors Nen balls possess almost every single property of plasma, and virtually none of the properties of energy.
