Treyarch added a classic matchmaking playlist where skill was only used minimally and it was absolutely fantastic. Getting into a game took a few seconds and it didn't feel like you were getting screwed by the matchmaking system if you did well, plus I was always in lobbies with a ping of around 9ms rather than it jumping between 9ms and 40ms. It was actually fun. It shows just how ridiculous SBMM is in this COD and how the system will prioritise skill over connection.
Hopefully they'll use that system going forward but I doubt it. If they remove it then they're fucked IMO as they've shown players how the game could play if it wasn't for their SBMM system so those players just won't get the game.
