I gave up about 2 months ago. With such a laughable matchmaking system, the game isn't fun anymore (By anymore, I mean the last competitive option a random had. Squad Slayer.). Yes, I love being matched against a Nova+ team, and then being given allies who would betray me in two seconds for the sniper that they have no idea how to use. Good job matchmaking. Crappy, campy maps, armor abilities 343 clutches on to like a child to a teddy bear, and the worst ranking system to even see the light of Halo.
All that's left that is normal Halo (not SWAT, snipers) is MLG, and Invasion on good days. And I don't even have a team anymore, they quit for Halo 3, or moved on to new games.
