I agree that halo 3 had the best playlist set ups. 4 needs rumble pit/ lone wolves, doubles, a fixed SWAT playlist, fixed snipers playlist and grifball. A party playlist, featuring a mix of fun game types, like fiesta, would be awesome as well. Hope that these are implemented, or else I can see many people leaving. 4 is a great sme, slightly let down by a lack of playlists.
