The December patch is simply terrible. And I'm not talking about the balance. You've simply broken he game e.g. I've had like 5 synch problems after december update, every one happened during a 4x4 match, that was going to end up in a victory for my team. I've played the game for at least 2000 hours and have never had synch problems before. I know such a prblem was the case for the COH1 and it's maphack related.
P.S. Even the most terrible balance could be adapted to, even the most reckless cheater can be defeated, pity you've got no tricks to fight synch problems.
