I don’t know why, but since Halo Reach there has been a weird tendency not to include team doubles in the original pack of playlists.
Team doubles is one of those playlists which should be considered a core playlist and I don’t see any reasons why I should wait several months (or maybe more, still no TD in MCC) to get it.
It’s my personal favourite and I know lots of players who feel the same, TD has always had good numbers in MM. It’s easily one of the most popular playlists in Halo.
343, please make TD available on the launch day!
