I don't believe everyone needs access to every mount. It's ok that there are mounts that you can't reasonably obtain. As such I'm against the idea, they are all ugly mounts by todays standards, you don't need them for anything. And if you are collecting for collectings sake, then rare items are more fun to collect. No-one cares about obtaining their 4th recolor of a boar that took 10 minutes to obtain (collection wise)
