Currently, red has a weird height+sightline combination advantage straight out of spawn over B that's difficult to work with. I added a bit of cover in front that might make it safer to stand on the point and less desirable to hold up back next to the spawn doors.
I added and moved some geometry in the yard outside of B to give Blue some height to stand on since for the most part it's lower than Red's stuff.
I moved and pitched the open window at A down a bit and shrunk the room considerably to make it more difficult to camp while sniping Blue's forward. Assisting this is a larger/longer point A, which provides more shelter to the area underneath.
Hopefully setting up in the window room at A is still useful without encouraging too many Red Snipers to camp.
