Sometimes games go on forever and at the end, it can be difficult to remember how players who have been kicked out during the game have been playing.
I have the impression that most people dont leave feedback to others in such case.
It would be helpful to be able to leave feedback to someone as soon as he's eliminated from the game. It does not matter whether it will need to wait until the end of the game to be published, but at least it could be there on hold.
