frootloopsEvery other Round Robin-esque ranking system/bracket in games has always used W/L over both H2H and Points/Game % in almost every example you could possibly bring up, I don't know why points being the main decider was ever considered a good idea to begin with.
im pretty sure they made the point system with the thought of stopping stalemates in matches but without realizing that theyre creating a bigger problem than the one they are trying to solve
