Siege of Cairo out of bounds

On siege of Cairo it's possible to climb up onto the roofs of the first sector. This makes it nearly impossible for the opposing team to fight back as ur near unkillable and can use deploy beacons to repeatedly spawn up there. You can also destroy the things used to climb up to stop others from contesting you up there.

Video attached - you can parachute to multiple other buildings from the spot I get to in the video
