I have gone through all of the material regarding the mount and hitching rail and nowhere does it say, either in game or on the store, that the hitching rail is not able to be used in RBGs. I made the purchase of this mount with the primary intention of having it for my RBG team.
I had a chat with a GM in game about it today and the only suggestion he had was that if enough people complained about this on the forums, they MIGHT do something about it. The fact that they market a mount with the ability to share it with your group and then make it non usable in one of the main group activities in the game is just ridiculous.
