Possible Solution To Terrestrial Mount Flying?

[Kaitoo]

Well if they created a system like this we could have any mount ever and not have to worry about how to make it fly/swim.

What's broken is the ability to make more ground mounts and it be fair.

Well i like ground mounts becuase... you know they are ground mounts?

i mean with that sugestions, why not make the Player Character fly?
