Rank, to be honest I'm sort of happy that the Onslaught is in its own playlist. I have the map pack. Problem is the number of lobbies available for me to play in, especially after midnight, in standard Core is not that great. Fracture that to DLC only gamers....... I'm really going to struggle playing. OH yeah - Xbox One form the land downunder.
I think they will really need to add the option to turn on/off dlc.
