Mount changes no longer available
Swift Zulian Tiger Zul'Gurub is changing from a raid to a leveling zone in 4.0.3, and this mount will no longer be obtainable.
Swift Razzashi Raptor This mount will also no longer be obtainable after the change to Zul'Gurub.
Razzashi Hatchling With the change to Zul'Gurub this non-combat pet will no longer be obtainable. (Update - The Razzashi Hatchling is still obtainable in Patch 4.0.3a)
Tome of Polymorph: Turtle Mage This tome will continue to be available through other means.
Crusader's White/Black Warhorse and Swift Alliance Steed/Swift Horde Wolf As the attempt-based tribute system is being removed from Heroic Trial of the Crusader, the Argent Crusade Tribute Chest will no longer spawn, and these mounts will no longer be obtainable
Reins of the Blue Drake This mount will once again be available from defeating 10-player Malygos without needing to use the Dungeon Finder. The Reins of the Azure Drake will only be available on 25-player Malygos.
Mimiron's Head This mount will change to be a very low drop chance when defeating 25-player Yogg'Saron with no Keepers assisting you
Invincible This mount will change to be a very low drop chance when defeating Heroic 25-player Lich King
Although we have no current plans to introduce new ways to obtain the Zul'Gurub mounts, pets, and the tribute mounts, they may return should we find a place where they fit in the future.
