A question asked via email this week on the podcast got me thinking: who is in charge of the orcs right now? All the other races of the Horde have their own faction leaders, but following Hellscream's defeat and the ascension of the new Warchief (following this paragraph, I will be using the name of the new Warchief, as Garrosh Hellscream has been available on LFR for a week now) this leads us to an unusual circumstance - for the first time ever, the Warchief is not an orc, and thus, not the direct faction leader for the orcs in addition to his role as overall leader of the Horde.
Now, for those of us who saw the cinematic, this question seems to have a simple answer: clearly Thrall is now in charge of the orcish people, yes? He is the first to kneel and proclaim that he will follow where the Warchief leads. However, upon several rewatchings, one thing is clear - he says he will follow. He doesn't claim to speak for anyone else.
This leads us to another question - if Thrall isn't to speak for the orcs, then who is? Of course, another question we could ask is, does it matter?
