To be honest, for every time I have played this map, only once have I seen the last point capped. Or rather, the second point. It is the second point in the map, so if people would play your map often, they would see the first 2 points more then any other point. So make it easier to cap them or the map will become incredibly boring, very quickly. Just make it easy to cap by giving the blue team for space, more health and ammo and a one way door to give them an incredible advantage. Or make it harder for red to reach/defend the point or the attack lanes of blu.
