Flying in Azeroth

How about enabling flying in Azeroth. I'm sure most people want it.
(And dont give me this is not a Blizzlike feature. We have Transmogs here in WOTLK which is already not a Blizzlike feature.)

Everybody loved being able to fly at Azeroth in Cataclysm and I cant see any reason why people wont like it here. Would make the game more easier to play.
I know it would mean a lot of work for the staff but something amazing as this is a must XD.

Yes, I will give you the "it's a custom feature." The difference between this and transmogrification should be more than obvious.
