Yeah Dominion had a lot less drops in the first two tech tests. The beta seems to have a whole load of network bugs. Maybe it might be server stress. But I have been locked into a state of forever joining games with the only option to Alt+tab and close the game.
Little trick I have found is to quit when you see a lot of people being dropped from the session then get into one that is about to start.
This needs to be fixed asap.
Once in commence chasing the new guys around. Had fun once I got in.
