Infront of the Citadel there's a blind spot where you can not attack an enemy because of the towers in the way, if we could somehow access the tower and use the arrow slits,
Perhaps have the door open and then have the wall present but being able to shoot though it? I'm sure the developers could think of a better way to fix it.
The reason it is a problem is that someone could stand there all day, and we can not get to them, although the arrow slits in the towers are designed specifically in order to target that area, anyone knowing this could abuse it, and hide there to recover health or hide and then return to attack the Garad Garrison
