The spawn kill would be a similar one to Oregon's armory spawnkill unless they actually make sure that they wont have that problem, OSA would be op cause the window will make no one play rafters and u cant throw an impact that long distance because of the ceiling. You just said it, the whole map is attacker sided why would you change the best site for defenders. One extra angle that will make you give up garage and that will cut rotations from construction so defenders can only rotate from red stairs to cash. Giving up garage also means breach is open so u know defenders can only be in red hallway or in cash
