Halo 4 needs a ranking system to keep the game alive,not be boring and dull after playing the game for months to come.
As everyone can tell the population on-line is very low and i feel it is because of the lack of a ranking system. we need a ranking system that was placed in halo 2/3 or something similar where the game felt alive fresh and you had some type of incentive to play the game more and win.
This game also needs a ranked/social playlist to keep everyone happy as once before
