Oh so you're saying the cloud serpent wire frame was in the game prior to heart of the aspects? Don't twist words, I never said it was part of the plot or anything of the sort. Heart of the aspects was a teaser from blizzard who finished working on the cloud serpent model in MoP and decided to modify it a bit for CURRENT content and release it for some extra money.
If you honestly say the heart of the aspects mount has nothing to do with the cloud serpent model we have to today. You're wrong.
Well ... you are wrong. lol
I wasn't twisting any words, the model was created for the Dragon Soul raid and released when Dragon Soul came out. If you watch the final cinematic, the thing that shoots Deathwing is the Heart of the Aspects, and just as the name suggests it was the powers of the aspects (the 4 DRAGONS) hence why the 4 aspects are now powerless and also why the Heart of the Aspects looks like a dragon.
It doesn't have a damn thing to do with MoP or Cloud Serpents. It wasn't a teaser. Any person with eyes can clearly see that the models look nothing alike, animations aren't even similar, the skeletons are completely different, the textures are not the same. Unless you think serpent-dragon = MOP SPOILER then there's no other similarity between the mounts.
