From what I understand, 343 has implemented a system of weights that attempts to place you in games where the other players have the DLC maps (if you have them). In some instances, this system seems to do a noble job; I see many of the anniversary maps, for instance, in the Team Slayer and Team SWAT playlists.
When my friends and I play in ths Invasion playlist, however, we don’t have much luck getting Breakpoint to show up in the voting options; we see an apparent disparity between the weighting system’s success in other playlists and its possible lack of success in the Invasion playlist.
Has anyone else had more success getting Breakpoint to show up in the Invasion voting options? If not, perhaps we could ask 343 to take a look at the weighting system for that playlist to see if it needs some tweaking.
