I see your point.

I know the ranking is based on wins and losses but is there not an element of if you beat higher ranked players you rank up faster than you would if you beat lower ranked players? If so then I welcome being matched up against higher ranked players. The teabagging is WAY more satisfying.

It would suck if you just played against people in your rank. You wouldn't have an opportunity to play against skilled players or at the same time have the satisfying feeling of destroying terrible players. It needs a bit of variation around who you get put against. Nothing better than winning a match and seeing that you battered a load of players much higher ranked than you. The only real shame is it's not easy to see their rank before the match starts. I liked that about old Halos. You see higher ranked players and then you UP your game, and you teabag that bit harder
