Mind if I ask you guys a question? I know, this represents Garrosh stylizing himself as Mogor the Ogre with only one head, but I'll get to the point. What would it look like if Bethesda and Blizzard combined The Elder Scrolls and World of WarCraft into one game? My best guess is that both Azeroth and Tamriel will have an all-out war with each other. I know, a lot of you will say that Bethesda "will never make that mistake", while Blizzard is floating well over a sea of troubles.
Not going to happen. Blizzard said at the lore panel at blizcon that there is no redemption for Garrosh. He is going to Old Dranor to raise an army to attack all of Azeroth he want revenge. They also said he will be taken care of and the end will be satisfying to those who saw him as a bad guy all along, and that he is not even close to the boss of WoD he is down at the bottom as far as bad guy importance in WoD.
This story is much more comparable to Arthas, in that up till this point he was just a Warrior of his faction and MoP leading up to the seige was similar to Arthas leading up to the culling of Straholme. Now WoD will be his raise an army and get revenge.
On a side note they did say that Zaela is coming with him so there is a chance a very small chance there will be a little Hellscream in the future.
