We are not talking about a too narrow range obviously. The ridiculous thing is that you can matched up with a dude with 0 rating when you have 500+. But a match-up between let's say a 180 rating and a 320 rating should still sound ok, same goes for like 400 vs 550 or 80 vs 200.
I think that if there would be a +/-120~150 rating player pool you can get matched-up with, it would already be a lot better.
Please consider it, whoever will read this post =)
