I'm not sure if this has ever been suggested, but i think it'd be nice if there was an option that you could select, so that your rating did not go up if your opponent timed. I feel like my rating fluctuates too much because people keep timing out, so i get a high rating, then i lose because i'm not good enough, and my rating drops. It's not somthing vitally important, but i think it'd be a nice option to have. Just a thought.
