Uneven teams, party separation, ranks reset, long search times, glitchy leaderboards (such as killed most by yourself), cant join open custom games in session, max players is 10/10 and occassionally ends up 11/10 in a game, post game lobby doesnt have a total team score which causes you to have to calculate it yourself while checking the carnage report, the theatre never saves the previous game played without deleting 12 films from the temp file folder
it does annoy me that people get separated in games because i end up getting quitters on my team or derankers to help their friends win.
