While Leading the Cavalry required a wow gold player to stable 50 unique mounts.
Patch 3.08, which is currently on the Public Test Realms, includes a new achievement called Mountain o' Mounts. This is an extension on the old achievement Leading the Cavalry. While Leading the Cavalry required a wow gold player to stable 50 unique mounts, Mountain 'o Mounts really pushes the bar. The new achievement requires 100 unique mounts. Probably when this achievement was announced the first question most people had was wondering if this is even possible.Obtaining 50 mounts before WotLK hit was considered a major feat, essentially requiring exalted status with all home factions. Just like with the old achievement, Warlock and Paladin and Death Knight class special mounts count towards the total.Because there were less mounts obtainable by the Horde faction pre-WotLK, the following list of mount totals is taken from the Horde perspective. Before WotLK came out, the average Horde player had access to around 66 mounts. Or 45 if you happen to be a Tauren. These are non special mounts that can be grinded for through either rep or token turn in. There's around 10 more mounts of the rare quality that could be achieved through running instances, and even a few more that were rare to start with and can't be obtained anymore.So starting from a base total of 66 mounts, poor Taurens, and adding to it the Albino Drake you'd get on the way to 100 anyway, there needs to be at least 33 new mounts in WotLK for the average player.Short answer, there aren't.
