Yeah, most of them do.
But Zafod doesn't. A couple others are pretty bad. Some have a chokepoint that doesnt' help either team, and the map just stagnates - nobody can break through.
And one of the beach maps (overlord, I think) has a serious problem in that the Axis are automatically killed by the system if they try to go down onto the beach, but allied snipers can lie under water, where they are impossible to see, and clean the clock of anyone on the bluff without ever having to fear being shot.
