Personal opinion here on the Social Team Slayer Playlist here. In my opinion the Social Team Slayer playlist should just be Halo 2C, 2A and 3 with Halo CE and Halo 4 getting their own social playlists. The reason I say this is because if someone wants to play Halo CE or Halo 4 in a 4 vs 4 setting socially they’ll just go to that respective playlist. That way Halo 2 or Halo 3 player’s can get more of their respective games in the Social Team Slayer Playlist.
