Greek,
Yes; another hole in the cheese, but ATC are entirely justified if they see a need to order a go-around. If two pilots cannot handle such an order, then it is down to them and their training alone, NOT ATC.
As I say, (and you agree), SIM training has become so involved these days that basic flying skills are rarely, if ever, given sufficient practice time.
I mean, a concert violinist - or any professional musician - can, and often does practice every day. BA pilots can use their SIMs during down time, but how are most pilots supposed to keep their skills sharp when they do something just once or twice every 6 months?
