I'm finding the post-patch experience MUCH worse; what I'm seeing however is clearly different from before so the details might give a clue to someone.
Before the patch I had problems at first, then forwarded ports 6073 and 6100 - 6200 and after that things went well, apart from too many bots in the Pantheon. I've played games whenever I wanted to, very successfully. Lots of fun.
Now I can't play Pantheon at all. Once a game starts to be matched, I was delighted that in each of the four games I tried every place was filled with humans; also instead of some doing nothing much they (almost) all seemed to actively try to connect.
Strangely although several connected to me, I could connect to - at best - one other player. After a minute or two the number of players fell away I suppose as people quitted. Several other players had limited connections connections to each other as well. In three of the four games I was kicked after a short time. I've never been kicked before.
So, despite seeing more humans than ever before, the game has gone from okay to, literally, unplayable. I can't join a game.
I wonder if the ports that I need to open have changed? I've certainly changed nothing at this end.
Suggestions welcome. I'm in England, using NAT behind a Draytek router with ports open, and tested, as above. No antivirus / firewall on the computer.
