This is very frustrating, I have had about 6 out of 8 games where while in a party of 3 doing 4v4 playlists, we get outnumbered and have to play entire games 3 on 4. It would be one thing if it was because players were quitting but its not, the matchmaking system is simply matching our party of 3 against a party of 4 and not bothering to fill in our fourth player. Fix this soon please, this is very obnoxious.
