If it were me, I would offer bonus banners for the point differential in a win. If your opponent doesn't clear anything, you get the banners of the difference in the score added on top. Easy. Because right now, just going by banners makes people just go all offense in clear and who cares. They can lose TWO matches and still rank ahead of me when I worked to BEAT my opponent if I happen to draw some ringers that set hard D. I don't know why the idea that winners should rank higher than losers is controversial. It's so stupid simple of a concept.
