other airspaces have to deal with different aircraft types aswell and even 330'ies can fly 3deg paths with adequately trained jockeys and appropriate sop's. so that's not the problem.
it's basically about control and coordination. as long as three to five proud acc's mingle in a airspace of suitable size for only one, nothing will improve. especially if one neighbour, signing the paycheck of the big viking, enjoys spoiling the party of it's hated northern competitor.
the only viable solution would be one control for the uae. but as the probability to this happening is as high as ey and ek will ever join forces, we'll keep on enjoying the local rivalry from the cyclone over sheik zayed road right down to desdi.
keep it safe
