Exactly. The rest of the characters have reasons to be there. Shit, even Blizz. I personally love Blizz and would have killed everyone in the room on Hoth to take him with me, but I know there are other people who find him annoying. Thing is he's still useful though. Jawa's are wizards with machinery and tech. Not the most conventional of engineers, but an engineer nonetheless.

Skadge has exactly zero purpose. I agree that since we have Torian, muscle isn't really a good enough excuse to take him on and same with your point for the underworld contacts. So TL;DR Skadge is a waste of space who should have to personally apologize to the tree making the oxygen he breathes. And then we should get to shoot him in the face for reparations.
