I believe that you should add a DLC only playlist in the same way that there were Content Collection specific playlists, only this time around it encompasses all DLC and only DLC content. Those who are missing any content would not be able to enter this playlist, just as those without Elite Premium were excluded from the Elite Playlists.
Sometimes I want to play my DLC (I have all 4 Map Packs), but only my DLC. Other times I want to only play on the original maps. You guys at Infinity Ward/Sledgehammer/Raven were kind enough to include an "Original Maps" button, but I there are times when I only want to play on the DLC Maps. What does everyone else think?
Thank you for your time and I hope that you can find a way to include this in the game.
