No Ranking system. everyone I know that used to play and love halo 2 and 3 no longer will even think about picking up the sticks and playing halo 4, the reasoning behind it is 8 out of 10 times the teams are lop sided with people that play competitively and people that don't. The direction you brought Proving Ground is great with no radar it makes people want to and have to communicate again, but the problem still arises that 8 out of 10 games the teams are completely lopsided and takes the fun out of the game from the people that want to play competition and also the people that just want to play socially. I'm not asking for a ranking system the ball was already dropped on that one for this game but more asking to make sure there is one in the upcoming games because it honestly ruins the whole experience of the game without one!
