He can negg someone with extremely limited condition which are:
-having a public
-using the nen of other members of the PT
You remove one and he is basically dead, uvogin is objectively stronger than him in a real fight. He and his overwanked group gonna be cooked soon and the zoldyck will carry. If chrollo is a 100, ging is a 200 at the very least, everything chrollo can do, ging can do it better. He is smarter, stronger and way more experienced.
