Multi Team, hands down, the best Halo 5 Social playlist. The feel of the playlist differs from your normal arena play and that’s a great thing. The maps are not so congested and full but there is never a feel of it being too empty. The gameplay is both crazy and layed back which is hard to get in any other playlist. Spawns need improvements but otherwise it’s a amazing experience. Brings the best of competitive and social together. Also, REQ points should be buffed to around 1000 a game.
EDIT: Addition of objective gametypes would be great too. I can only think Oddball would work but it’s still a start
