You have to fly into KUL to be grateful. 3 runways, 2 with ILS, with no arrival at 32R they will still cram every low co into 33 which is 24/7 in mixed mode operations.
And worst is they dont even accomodate wind change. Reason given controller in Subang Center still find it acceptable and to minimize airspace congestion due to close proximity to SZB. I bet they havent been to Singapore to see how congested and small the airspace is.
No problem with SIN controller. Easily the better ones around this region
