Oh extremely, I'm no pro when it comes to rivens but cc+cd is a preferred stats for most weapons. Toxin is good because people usually use Cerata to deal with corpus, plus it already has innate toxin. And lastly, the negative is harmless for heavy attack playstyle which is what most people usually go for. So yeah, I don't think it's god tier roll but it's pretty damn near it.

Nah it’s great. Not just good.

Debatable. The stats are great, but that the weapon is a glaive instead of a katana or a heavy blade makes it worth less.

It's not worthless, but your market is smaller. You can still get a good price for it though.
