The best departure gates from the passengers point of view are the ones in the terminal proper. The ones that are far flung are less so, and do need attention. I use the airport frequently and tbh arrivals I have never found an issue, I think they could do with more space and I'm sure the powers that be are aware of it. Having said all that I have often been off the plane and indoors having a cuppa in under and hour which is good going by any standards.
