halo 4 map packs dont work

i cant play my dlc on any playlist unless its in the crimson playlist or custom games i want to be able to play on every playlist and i cant i have all three map packs

The DLC maps only show up in matchmaking if everyone in the lobby actually owns the maps. Due to this game’s low population, and (presumably) low DLC sales (based on low DLC population), DLC just rarely shows up.

This is because not many people have the map packs and at least one person in your lobby doesnt have the maps causing them not to appear.

Your best bet would be to find a nice group of people that have the maps. That should increase your chance of seeing the maps, and also give you better probability of voting for them.
