Is it possible to...

Only match you with players that have the same DLC as you?

So, let’s say the only map pack I have for Halo 4 is Castle. Could matchmaking be changed so that if I click on Big Team Battle it will only match me with people that also own Castle?

Obviously if I was with friends that didn’t have the DLC then this would be disabled, but I feel like if the game did work this way then people that own all the DLC would actually get to play it in matchmaking and there’d be one less thing to complain about.

It is entirely possible, but it would drastically slow down matchmaking times.

The better option would be to have a toggle for this option with an obvious disclaimer that Matchmaking will take longer.

Issue is, it would require UI changes to implement it and at this point in Halo 4’s life span, I doubt they’re going to dedicate the resources to doing that.
