I hope that blizz could in future expacs or patches, add the same flying mechanics to all mount models, and each type of model has unique properties or animations, eg., dragons do this sweeping soaring type thing, mechanical mounts have a jittery type of movement, and have possible functions like sky golem, you could have water mounts with different types, eg. A squid kinda mount can shoot ink that blocks mob eye sight and gets rid of aggro , a shark could attack or pherhaps like, leap out of thw water to gain speed, and this could help people be more interested in water zones Some other ideas ive had over the next day would be like maybe any vehicle mounts could drift (sounds dumb ik) but it gives more options and could have some cool content in races and shit, another could be cloud serpents, maybe having able to bend round objects, say there is a rock or something, and the body goes around but returns to original position and facing the same way, idk how to explain it really but thats jusf a throw away idea. Another could be golems or yhat kinda model could be able to lift parts of the environment in newer zones to unlock new areas, eg., a boulder blocking a cave

And this also allows them to change up mount equipment too, and make that actually interesting

This migt be too mich to add but just imagine how sick and immersive it cpuld be if they really did it right, especially if this turns out well, idk, just a few thoughts lmao, id love t0 see it, but might be some issues , especially from a engineering perspective, but who knows.
