I propose a fair compromise; Revert flying speed to what it used to be prior to the Warlords of Draenor nerfs when they changed the way mount speed enhancements were calculated. 310% speeds after that effectively became slower than 280% speeds were in Mists. It's really too bad the community didn't make a big deal about it the way they did about the water strider mount in legion, as it effectively rendered achievements like "What a long strange trips its been" a waste of time.
