Halo needs a tourney mode because you'll instantly get into the next match when a round is finished. for this to work you would have to be able to pick what gametypes and maps go together and Halo on XBOX ONE will most likely have spectator mode, so I think the spectator should be able to look at the bracket on the pause menu, and the player should be the one who sets up the bracket not the system. Please help get this known I think this would help Halo.
