Finding games isn’t as difficult these days but the problem is if you are playing with a buddy and trying to rank up, it will eventually split you up and post you on opposite teams.
Last night a friend and I were having great games by doing the following:
Exit to the dashboard and restart the game. If you don’t know how to do this you simply click start on the game window in the dashboard and select quit.
Boot the game and search as normal in a party. The first game you find after restarting will always put you on the same team as your party (at least with two players I haven’t tested with more).
Once you complete the match and view the post-game report, follow the first step and restart the game again. When you both restart the game, it resets whatever parameters are preventing it from working properly and you won’t have an issue with matchmaking putting you on separate teams.
I understand this is annoying and completely ridiculous but it definitely works and is a temporary fix that will allow you to rank up with your friend without frustration.
