First of all, I have played the Blitz and there was less lagg in that and I realise its the first day and everyone is trying it at the same time, im sure the Uber Entertainment team are quite overwhelmed. However I havent finished one game of MNC yet, it keeps disconnecting about 5 - 10 mins into a match. When it happens everyone stands still and i get the cable plugged out icon in the corner. Then usually its follow by a "lost connection to host" message. Im really hoping that this issue is because everyone is trying to host when they cannot get games to work themselves and they clearly have not managed to port forward properly. I was worried that it may be because my uni network blocks every incoming port imaginable however I seem to be able to join games, just not stay in them long enough, and I can see that there are many threads talking about connection problem.
I got disconnected from my first (and so far only) Crossfire match as well. It's very well possible that the problem is entirely on my end since my internet connection sucks. Props for the team though, it works at all. That's not a given with the settings my ISP runs.
