I say three playlists Mayhem, Quick, and Competitive Competitive scoring is based on wins 5 point and losses -3 points, ties are 1 point. First 10 games you are put into games with people who haven't completed their first 10 games too, after that you are matched with people with your score. Rewards would be competitive shaders, armor, and weapons. You get a reward every 25 points, no farming the same score twice. It's a start, I'm no game designer.
