I feel that when the Halo 4 team playlist returns Infinity Slayer should be either replaced by or joined by Legendary Slayer (BRs). The playlists that feature arena styled gameplay tend to be the most popular in the MCC, and the Halo series in general. Halo 4 is (in my opinion) a lot of fun on it’s base game type (Infinity slayer), but is definitely much more fun when it’s played arena style. This would probably increase the amount of players in the Halo 4 playlist, and would probably please a lot of fans.
