I.. Somewhat agree, I think, although I'm not sure if this is a case of his nen becoming stronger, and not just him learning something about his ability that makes him use it better
ie learning a new skill and not just a power up
It's not like what he did learn was really that amazing to me, just happened to make rubber limbs because he lacked some and noticed that they improved his movement>>157136810
Yeah, I don't disagree. Although I guess that's been part of all of HxH. Everything is anticlimactic basically. Same with greed island where he could just use a card to heal his hands.
