my impressions on the update so far:
haven't actually been able to try any of the new weapons myself as i can't unlock them - the game has yet to allow me to connect to any MM servers
the new flamethrower can go forget itself. that thing is the devil.
i got an 11 kill streak with a phlog i got from an enemy pyro. it turns out people still don't know how to counter it
i met some spies that still havent realised that the ambassador isn't a sniper rifle
