I think the controlers do a very good job in DXB. A hold is almost non existant even at the busy times. As for the profiles, vectors and speed control when it is busy, I say they see more of the picture than we do, so I just follow and let them lead me in. They always get the message across when we are get high or low on "their" profile (sometimes you have to read between the lines). As for the rare instance when we are arriving in the pattern with close to min fuel, if you let them know I'm sure they will do all they can to help out.
Keep up the good work guys.
