Ok, you appear to have missed the point here IW, so let me help you.
1: In the DLC playlist, we only want to play DLC. Not vanilla maps. If I wanted vanilla maps I wouldn't have gone into the DLC playlist.
2: Overkill on the playlists much? All we needed was DLC Team Deathmatch (TDM and Kill Confirmed), DLC Objective, DLC Hardcore TDM and DLC Hardcore Objective. We don't need nearly a dozen playlists just for the DLC.
Please try a bit harder next time IW. Thanks.
