There are playlists on this game that almost no one is playing, where it takes 10 minutes to find a game, but 343 removed SWAT which always had tons of players because it is a Halo staple, a non-negotiable playlist you CANNOT just remove. Seriously, put it back up I know several people that aren’t playing the game cause that’s all they tipically play.
Feel free to use the existing feedback threads in the main MCC forums for this type of feedback. Closing it off as it’s not a support request
