Example to keep it simple: I'll go to crashsite/spears and see that there is 10 players and 1 game active (makes sense) so when I join it should make me the 11th player and connect me to that game, but instead it creates a new lobby were I'm sitting all alone. So it now reads as 11 players 2 games......stupid right!
No new games/lobbies should be allowed to be created unless the player count goes over 12. And no one would be sitting in some empty lobby that shouldn't have been created in the first place.
Every game mode does this which is really a huge reason (in addition to the hosting problems) why people give up for the night or have left all together.
What does it take to patch matchmaking? Could it be D patched?
