In Halo 4, since they are doing this whole “Red vs. Blue and why they fight each other” thing, they should make Red vs. Blue tournaments.
To elaborate, every week/month, you will choose the side you prefer, red or blue, and victories of each slayer game will be counted for which ever team won the match. For example, the red team won the match, so they earn one point. At the end of every week/month, the team with the most victories wins for that tournament, then a new one starts again.
