Is that a good idea?
Halo 2 had a playlist that was only full fireteam vs full fireteam, it was a DLC-only playlist. And it was motherf***ing tough as hell. The rest of the playlists were so well balanced, with the best skill matchmaking I’ve still experienced to this day, but that playlist was screwed up man. It seemed like the only people who played that were really really high-skilled teams.
Meanwhile, this didn’t happen in the team playlists where it could be randoms vs full team. And even those were really well balanced in Halo 2.
