Bad matchmaking

I’ve notice that I’ve been pit on the same team with same people against another team that destroys us every game and the teams don’t change. Is this just shifty matchmaking? Or am I just playing terribly with terrible people?

There is no “matchmaking” after the initial server selection to my knowledge, so it’s unsurprising that you play with the same people against the same people each game as long as you stay on that server. Try switching teams or switching servers until you find a good match.

Just exit and go back in and you’ll get a new team

You can change teams in game. It won’t always allow you too. But you can usually. I’ve done it to get into a squad with a friend before.
