I think an unranked 4v4 Team BRs playlist would be a good edition to Halo 5. I don’t always want to play competitive 4v4, yes action-sack is great and so is BTB but those playlists give you that Social 4v4 Slayer feel.
I would like this playlist to feature 343 maps and community maps, maybe add a few new community maps every few weeks to keep it fresh. This playlist could have variations as well, such as Halo 2 Team BRs, Team BRs Strongholds, Classic Team BRs, CTF Team BRs, and many more, this would make this playlist stay fresh as well.
I hope this could be implemented someday, if this doesn’t end up being in Halo 5 I hope its in Halo 6.
