SO with the new patch coming out, I decided to point out something that will make every mount hater cringe. Areananet supports the idea of mounts, and it is already given in lore, and this is evidence of this concept art: http://sphotos-b.ak.fbcdn.net/hphotos-ak-prn1/150926_10151300660039209_681568240_n.jpg
Should be interesting to see how they work when implemented
If you look carefully, you can see, that the guy is standing next to the horse but isn´t riding it. The horse got something on its back, what supports the fact, that animal are used to carry things, not to carry people.
