I understand the complexity of changing the rating after the game now it makes sense how this is unreasonable. But in a reply to your comment about trophy points, no, my reason for asking you to fix the points was for exactly the reason you stated. Balance. If FAF is not declaring the correct point allocation to the winning team then FAF is causing de-balance in the worst possible way.
I hear this statement quite often, but in reality players skill is infact judged on points, it also allows or dis-allows a player to join a rating restricted game. It effects tournament participation too for teams. So please don't trivialise the point's.
