343i has not put the update into all of the playlists, and probably don't even plan on doing so. These playlists are TU free: Team Slayer, Team SWAT, Team Snipers, Multi-Team, MLG, Invasion, and Griffball. All playlists have gone down to 85% bloom already (except SWAT q.q), but you probably didn't even notice that because they did it a while ago. The only playlists you could possibly be complaining about is Squad Slayer, BTB, and Infection. Squad Slayer and BTB are just for fun, if you don't like them go to Team Slayer, where everyone else is. If you are complaining about Infection, tough luck. You should have taken advantage of camping while you could. If you want to play DLC maps, then find people who have DLC and befriend them, and then play with them instead of being a random. The maps will show up once everyone in the lobby has a certain DLC.
Honestly, I couldn't be bothered to read your entire topic because I've read about 600 of the same ones in the waypoint and bnet forums, and this response is sort of a conglomeration of previous responses to similar topics.
