In defense of Garrosh Hellscream.
From everything I've seen of him, I think he's far from flat. When he spurned Slyvanas for using the valkyre to forcefully resurrect the dead, I was on his side. This was everything he had fought against in Northrend happening right before his eyes. He wasn't just objecting to be a jerk, he was standing for his own beliefs as well. His heart is clearly in the right place, but he's inexperienced. He's a patriot through and through, and he's suddenly been thrown into leading people in a turbulent time. He's reckless and hotheaded, but full of pride for his people and honor. He's a flawed character that I don't always agree with, but he's not the main antagonist.
That'd be Deathwing.
On a lighter topic, I can't wait either. I am loving my troll druid and dwarf warlock, and all of my old alts are getting love with the new quests as well.
My only complaint is that I don't like new Brill. I can't find anything, and the old inn was a good rp spot.
