Yes to exclusive class mounts, let's say HUMANS will have HORSES, BEARAN will have BIG BEARS and ORCS will have BIG HYENAS as race base mounts, simple models of those animals. BUT to differentiate from other HUMANS, BEARAN and ORCS you can get a basic class mount that is going to be the same HORSE, BEAR and HYENA BUT with different basic armor and summoning animation depending on your class that will be upgraded leveling up your CLASS RANK, let's say every CLASS RANK you get more pieces of armor for the class mount or it improves the armor look, like the images below, but for every class matching the class armor style.
You will have more cosmetics to sell in the Scars of Honor store, mount summoning animation, different dyes for class armors, different glows for mounts, armors, weapons, etc.
Fully upgraded
