So, it's basically like the way Cataclysm did. Increasing the original speed of all mounts after learning a higher riding skill, so you can ride even those mounts that look good to you without worrying about their slower speed. Of course, unlike Cataclysm, Master riding would not be available, you would only get it after unlocking a 310% mount (unless you would be okay with having it unlockable by buying aswell for Icecrown and Outland players). I don't know if someone suggested it already, but I really liked that system in Cataclysm and it would be really nice to see it here too.
