Dispatcher, my whinge, such as it is, is the lack of standardisation (or published information). WW is actually one of the more clear and straightforward places, but I've been given a ticking off for descending deadside - as you've been taught to do, at another airfield.
In my opinion, the best way to join a strange airfield is overhead, but this is a bit difficult if different airfields insist (a) on their own variation, (b) without publishing it.
