Well I had an idea awhile back and I thought maybe I would share it with the MMO Champ community.
The Idea was to take the neutral Goblin Factions or even just one of them, like Booty Bay. Give them a Mount Vendor that has the opposing factions mounts. Raising your Reputation status to exalted will allow access to these mounts! The idea came from the Horde Faction receiving the new Goblin mounts and the Alliance faction getting....well nothing from Worgen!
