Welcome back to The Queue, the daily Q&A column in which the WoW Insider team answers your questions about the World of Warcraft. Matthew Rossi will be your host today.
Skipping straight to the questions today, because I have a long answer incoming.
Do you agree with me that Gul'Dan should be the big bad of WoD? Every other end boss has had an excuse for their evil, they were corrupted. Illidan by fel energy, Arthas by Frostmourne and Ner'Zhul, Deathwing by the Old Gods, and Garrosh by the Sha. Gul'Dan is just evil, not sympathetic, just evil
Garrosh wasn't corrupted by the Sha. He wasn't even corrupted by the Heart of Y'Shaarj - it had a kind of malevolent memory to it, but it was the heart of a dead thing, it was not applying its will to Garrosh. What Garrosh Hellscream did, he did of his own free will, without being controlled or possessed by an outside influence, out of the sincere belief that it was the best way to help his people. If anything, Garrosh's greatest failing is that he's myopic - he cares primarily, indeed almost exclusively, about orcs and the orcish people. So you are mistaken in your assumption that Garrosh was corrupted - to him, the Heart of Y'Shaarj was a weapon, it would be like you stabbing me and someone arguing that you were corrupted by the knife.
As for whether or not Gul'dan should be the big bad of the next expansion - frankly, I would worry that the next expansion has too much already going on to give Gul'dan the focus he deserves.
