Maincell floor is not KOS, because first, it's basically the entire map lol, and second, it doesn't lead to any armory, or catwalk. If you say that maincell floor is KOS that means literally the entire map is... the room in pool is KOS, because you can only get there from a secret or the catwalk, and it also has a scout. I honestly don't see why you wouldn't treat the catwalk in pool as the same as the catwalk with one way. Your arguments are telling CTs to just restrict diving boards, but seriously. Theres no point restricting something that is already KOS, like I always see many CTs saying "Freeday, no vents no armory" or "Freeday except for KOS areas". Having to warning shot Ts for going into KOS areas like Manny said, is absolutely ridiculous. Just treat this catwalk the same as others. It's KOS, because the entire platform will lead to armory.
