i would like to see a rank (exp) system along with a skill (1-50) system, like you gain exp no matter the playlist or win/lose but your skill only goes up if your winning games and goes down when you lose more, obviously the skill system would be separate for each playlist. Kind of like Halo 3 but obviously not as broken. This way it would keep the hardcore AND casual gamers happy. basically just make it a mix of halo 2 and Reach
