@numilor Yes. You are able to change secondary class at a certain NPC. So you won't have to level up lots of characters to try the various combos :smile:
Secondary class may not be changed "on-the-fly", f.ex in combat, though. Also, you cannot change your primary class.
Breeding and taming primarily. They can probably be sold on the market. But there will also be some other epic mounts. Certain bosses can drop rare mounts. Epic mounts can drop eggs, which will give you a temporary version of that mount.
We know there are dragons (flying mount). Epic boss...
