Just a thought seeing as it has been a common theme. I just feel they need to somehow make garrosh more powerful seeing that as of now varian could maybe solo him, so how does he become a big boss we all need to team up on to defeat?
be possessed by the Sha. At this point it is looking doubtful that the Old Gods will appear in MoP.
As for what the Sha are, it looks like Pandaria is simply a magical realm whose inhabitants are able to manifest the emotions in a physical sense. So the Sha would be more like Darth Vaders apparition on Dagoba during Empire Strikes Back than anything else.
I didn't find the right solution from the Internet.
