My team played on this map last night and there were a few sightlines some of my teammates pointed out.
They thought this one was a little too long, and could be blocked off by moving that fence prop a little to the left.
This one gave my medic trouble because not only does a sniper in that tunnel have a wide field of vision, he is also difficult to get at.
This one on last gave all of us trouble because, once again, the sniper was difficult to counter. He could fire straight into our spawn. Same goes for the other spawn exit, although it's not as bad.
