I don't think Heathrow Tower controllers as a rule have as little understanding of wider ATC as you give the impression that you have. I think Heathrow ATC is doing an outstanding job.
I'm sorry that you found my post caustic. I personally found your assertation that you 'don't care' about the agreed and promulgated arrival rate to be extremely arrogant, and whether you like it or not does belie a rather insular outlook against the wider ATC perspective.
I don't think I've met you at a Network Management Meeting. I'm sure I'd have remembered it.
