343 you need to either randomize the levels more in multiplayer or bring back voting. It is getting old playing a level 3 to 5 times over before it switches to a new level. As for ranking you should count the ranks toward kills and deaths in a game type its not a players fault if he is a low rank but gets like 20+ kills and like 10 deaths and still loses causing his rank to build slowly. Respectfully if you would fix that your game would be even better.
