So while I was roaming around the alpha I discovered some rather unusual things, I don't believe that any of these have been reported yet so I guess I'll be the first.
I decided to check out the barrens and this is what I found.
Giant Garrosh and Varian fighting over a giant Jaina. "Wtf is this shit?" I thought to myself, but then it dawned on me, it's not them who's large, it's the Barrens that's small. That's right, Deathwing shrinks everything in Azeroth but somehow the NPCs are unaffected. Yes that's right, I managed to return Azeroth to it's normal size with some sandbox trickery and discovered this little item...
Deathwing is actually a vanity pet!
Then I discovered that the Kirin'tor are attempting to capture Darnassus with the help of Jaina's skill at casting Mirror Image and a little Necromancy and cloning.
So after all this excitement I went to Dalaran to chillax, but I found this.
Yes, Dalaran is invaded by monsters.
Now to give this thread a purpose I call on you to post your own faked Cataclysm sandbox screenshots.
PS. I found an unused Gilnean skin in WoW Model Viewer.
