Because as if getting to Changi was not bad enough for a 6:40am flight, now you have to get there for a 5:45am flight.....

As if arriving at 23:35 was not bad enough, now you arrive at 1:15am

I remember it being a pain in the ... getting to SIN for 5am to check in - no public transport at that time - meaning a (extra priced) night taxi, or a shuttle van at about 4:30, now thats gonna be 3:30am from your hotel!
