Nah, they should go with a ranking system more similar to Halo 2's system. Halo 3 basically allowed people to win 40 games and not rank up, then lose one and rank down twice. That's just flat out stupid and inconsistent. I don't care if it takes one game to rank up or down, or 5 games, or if it works on a sliding scale, as long as they have a fixed system that rules out bull**** from happening. The true skill system is too flawed to be kept.
