Manhattan Bridge remove helicopters

I agree. I joined a match yesterday and since a minute one enemy attack helicopter never left our spawn. There was absolutely no chance for our helicopter to take off as it was killed on the ground immediately on spawn. There is absolutely no way to counter this behaviour unless you are very lucky to land a RPG shot. To make things worse this helicopter flied very high so RPG shot was impossible. Lock ons would be useless as well due to many buildings that it can use to hide.
