The new mount system allows a mount speed be applied to any mount. That is good.
But the problem is, the change of speed is not only applying to movement speed, but also to
animation speed.
The animation speed of mount, especially some mounts such as
Jubilee Parade Horse and
Blue Ribbon Pig, are designed to look fine with their original animation speed. With the change of speed be applied to animation speed as well, mounts' animation speeds look unnatural. For example, after Jubilee Parade Horse and Blue Ribbon Pig be applied 110% movement speed, their animation speeds are becoming faster as well and look like they are in fast motion, that makes them not cute anymore.

If the animations wouldn't speed up it would look even weirder because the mount would just ski around.
