4/5 times I try to join a game in fullscreen it just freezes and never loads. The only way around this I have found is to try and get it into windowed mode, which is buggy and only works 1/3rd of the time, the other 2/3rds I have to log out of my windows and log back in.
On another note I got the socalled best merc loadout in cobalt for the defualt guy.
