This is how it feels on live now after finally trying the Soar ability, even as just a simplified version it immediately made me hate coming back to normal flying. I can not wait until Dragonflight comes out just so I can spend time flying around, it's so refreshing. I swear, this better become evergreen and the start of 'mount classes' in Warcraft just like how they have a variety of 'mount classes' in Guild Wars 2.
I really hope that by the end of this expansion, all of the Dragon, Pterrordax, Gryphons, Wyrms, and Protos have their animations retargeted so they can be integrated into the new flight system. Then over the next few expansions, they should slowly come up with other 'mount classes' for mounts that don't fit in those previously mentioned classes. I'd love to see all sorts of new methods of traveling.
Dragonflying is probably the single most refreshing updated mechanic WoW has received since launch and I hope it does to travel what Mythic+ did for dungeons.
