Congrats Blizzard, you're 2 in 2 on bad decisions today
What's next? The epic cooking recipe will be available through other means? yes of course it will who am i kidding
What will you change your mind about next? No Shattering? Cost too much? People will QQ too much if their favorite zone are destroyed?
Seriously stop changing your mind and stop making things always EASIER for all the casuals in the world who were too lazy to grind the Shen'dralar rep or the razzashi raptor from ZG, those 2 things have been available for so freaking long if they don't have it by now they deserve to pay the price, either by missing on a Feat of Strength or literally pay the big price.
Since you all seem to have selective-amnesia here is the OP about things being removed:
"As stated in the Under Dev page (http://www.worldofwarcraft.com/info/underdev/), patch 4.0.3 brings about The Shattering, a cataclysmic event that will forever change the face of Azeroth. As we prepare to raise the level cap and introduce two new races with the Cataclysm expansion, it's important to keep in mind that the game world is going through tremendous changes that will affect the availability of certain rare mounts and items.
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.
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.
This mount will change to be a very low drop chance when defeating 25-player Yogg'Saron with no Keepers assisting you
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.
They didn't change their mind about the pet. They stated they would possibly find them a new home and re-release these items if they could. They did exactly what they said they were going to do. Anyone who is upset by Blizzard following through with their original intent is just mad cause they won't be able to (essentially) scam people out of money by trying to sell this pet after it's removal. Honestly, you have no reason to be mad at Blizzard for this.
