Escaping is fantastic, I can thoroughly recommend it. Good for the mind and soul!
Husky seems adamant that EGAA arrivals steadfastly remain above 4000 until far away from the city centre and never go below 3000 at night. All those conversations I have had over the years coordinating descent to lower levels were obviously a figment of my imagination then.
As far as the Class D airspace issue, worth bearing in mind the majority of Northern Ireland airspace is uncontrolled and is likely to stay that way. The Class D already there is certainly piecemeal but it largely works.
