Certain mounts and items no longer available in patch 4.0.3
As promised, Blizzard has provided a list of the mounts and items that will no longer be available as of patch 4.0.3, The Shattering. The brief list is below, followed by the full Blizzard statement after the break.
Swift Zulian Tiger and Swift Razzashi Raptor are no longer available.
Razzashi Hatchling is no longer available.
Tome of Polymorph: Turtle will continue to be available through other means.
Mounts from Trial of the Crusader will no longer be available.
Reins of the Blue Drake will return to their place as a 10-man rare drop from Malygos. The Azure Drake will continue to be available in 25-man mode as normal.
Mimiron's Head and Invincible will be rare drops from their respective bosses on hard mode.
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.
Tome of Polymorph: Turtle
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.
