I am glad that this was done, so people with the expansion experience it as part of the core game. I've always been tired of buying dlc maps and not having them in regular rotation (this goes for any game), and I need to play some specific playlist that may include gametypes I don't like. Or not having my new strikes included in nightfall content due to player content differences. It affects both sides negatively, but the side that pays shouldn't be the ones neglected.
