Last night I was trying to play some Halo MCC Multiplayer. When I was searching alone for games, I was able to find a game within 30 Sec to 1 minute every time consistently for 2 hours. But when I joined a party with one other player, it took us 2 hours trying to get one game. Further, I encountered the need to reset Halo MCC several times, since it would get stuck in search mode and kick the other player from the party. Also, having a hard time to even join a party with one player took us more than 30 min. Both of our NAT was open and we had excellent internet connections. When I was playing Multiplayer not in party, it seemed to have improved a great deal. My friend that had joined the party told me that he had been trying to get a Multiplayer game for a while with no luck. It seems to be different for every player. Not to mention all other little issues. It seems to me that even the Halo MCC software having stability issues.
