Mists of Pandaria was not about Old Gods until the final raid. The Sha were not the same as the Old Gods if we're talking about the theme of the expansion. There was the Sha, unique from the established Old God flavor, which wasn't present until essentially the end of the expansion when Garrosh became corrupted. The theme of Mists of Pandaria was not distinctly Old God related.
Congratulations, you pointed out the flaws in a throwaway idea. All you've done is prove what I was saying about your posting habits. It's not your job to prove people wrong buddy. Share your opinion but lose the arrogance.

Tinkers are certainly more relatable to Warcraft than Drac'thyr Evokers.
