Callyoushortly,
The problem that I think BF is getting at is the reluctance of a lot of pilots to go visual. Certainly not ATCs fault, but I could imagine a prompt by ATC might wake these people up. I do find it mildly irritating being held for 10 mins then getting extended vectors because the no1 aircraft would not go visual on a 30k+ CAVOK day. I am sure the setup of EDI causes a lot of the problem, but I think us pilots could do our bit!
