Would you like an in-game parser?

Yes, unfortunately. However, that is partially because they know that even if that one party won't finish the duty with them, the next one will, or the one after that. If they had little option but to get better or get locked out, they would actually try to get better, even if just enough to "pass" the "basic effort" the parties would expect.

No, I don't think that would work. The problem is that "git gud" process of everyone kicking them would be unpleasant enough to make them quit before getting gud. No one is forced to keep playing this game, and simply making things unpleasant for someone doesn't make them want to self-improve.
