I think this guy's experience and idea of the game was completely f'd because he was pretty much soloing the whole game since his team was completely stupid.
He should stop arguing and should play again with a team that doesn't end up retarded so it's not 1v(however many imperials there are) and he doesn't get the wrong idea.
I'm surprised he expects the game to be balanced in a 1vX game like that. How does he expect to take over all these bases and stuff as a single player and then complain because the enemy takes over what he kills, when he's just one player? He shouldn't be arguing, he should be trying again.
