Earlier this week, 343 Industries reduced the number of multiplayer playlists in an attempt to get Halo: The Master Chief Collection to run better online, after complaints from angry and disappointed gamers who found it hard to get a game.
But the collection still has huge problems, and according to a post on Halo Waypoint:" a larger Matchmaking performance-focused content update is currently planned for release next week".
If it's enough to fix the issues remains to be seen, we all know from recent experience that these things can take a lot of time and effort to fix.
As a result of all this, 343 Industries has also decided to delay the first pre-season online cup for the Halo Championship Series. The new date is November 23.
