Been playing HC TDM with a group of six since launch without any issues up until the newest DLC came out. Now it's taking 10-20 min to find a match, and the same to fill a game when it empties out. Everyone is in the US, has an open NAT, a good connection (10+ mbs down, 5+ mbs up), and all the DLC. Players that we invite into game often get an "unable to join session" message. Changing party host/search preferances, and different combinations of having/not having DLC doesn't make any difference. Anyone else have this issue or know of a way to fix this?
it happens to all of us, different gamemodes, different times. I blame the randomness of the interwebs
