I would like to see a way to easily filter your multiplayer partners. It is frustrating to always end up with hacks when you play a multiplayer game.
Nothing against hacks per se, we were all one at one time, but there are times when I am looking for a quick game and end up with someone with a 100+ average. Those games just go on forever sometimes. Sure you could cancel out, our remove them from your invite, but it would be nice not to have to be openly rude about it.
Just my $.02
