No. He’s saying that by default the only one here that might not be prenerf is the fellblade. The only prenerf characteristic it could have is a higher gv than is currently possible on q8 drops.
Sure, it could have a lower gv and still be prenerf, but it would need some other identifying quality for that to be the case. The only thing that could be is the inherent, but because it’s 15^50, we know that’s not an option either.
In any case, it's something quite recurrent in many conversations where some people devalue certain items because they are supposedly "not prenerf". Not everyone has the infinite knowledge of certains here.
Edit to respond to your edit: Devaluing something because it’s not prenerf is pretty typical/logical. Why would a fellblade, of equal functionality, that is still obtainable, be worth as much as one that isn’t still obtainable?
I’m not sure what your issue with it is.
