I thought of this great idea of pets having the mount skill. It should be a 5 dot rank thing, and also only for epic rank pets. Having the dragon pet would give you the dragon mount, unicorn giving unicorn mount, hawk giving hawk mount, and the sea dragon giving seahorse mount. Maybe giving some current mounts that w101 already has. Also, just to be fair, it only boosts about 20% speed?
I think that would kind of... kill off the extremity of mounts and the cute simplicity of pets. Pets and mounts are black and white. If you try to mixe them, you get grey, or many, MANY problems.
