I'll try my best to not turn this into another "We hate garrosh thread"
I'm really questioning Thrall's motives though.. I mean, I know he has loyalty to Grom Hellscream at all, but why is he soooo willing, even at the sacrifice of the entire horde, to leave Garrosh in command.. an Orc who didn't suffer with the all the other Orcs, learn humility and repentance from their demonic enslavement, and didn't even take part of the founding of their own city. It just sorta seems like he's plopping the entire fate of the horde in the shoulders of someone who isn't even a part of their culture.
I know the obvious real answer is a dues ex machina to force the horde vs. alliance mentality, but we haven't even seen how Thrall is rationalizing this. Although, it is kinda nice to bring his naivety to the forefront as a character fault to kinda faze out his status as a Mary Sue... ^_^;;
