So many mounts don't have footsteps in the snow. I've always felt it was off but now I realized that Chocobos and Players actually have them. You have the footprint graphics on the Mount Guide page, hopefully it's not that hard to add them into the game.

All in all, this is just a very minor feature. I really don't mind if this takes until 5.0 to be put into the game. But I'd love for it to be added.
