I've had the thought of removing Horve's "Factory". The reason I think of this is because the map itself is small and it is kind of crowded because the map structure is based on tunnels. Because it is built on this, it can cause a lot of spraying and it just isn't very good game-play.
My suggestion is to remove it and then re-add one of Horve's other maps. I suggest "Flesh" because it is just an incredible map and has excellent game-play.
