Heh, I haven't kept up with the current complaints but I am glad to see the vitriol from the expected ones on here.
Really though, is it any surprise that Vol'jin is the warchief? They've practically been telegraphing it since his run in with Garrosh. They could have gone with another orc, but that would have been expect, so they just went with the second most expected thing beyond Thrall taking the mantle again. Honestly, I am glad that it is a non-orc. It will help cement that the horde is a unified group that any of the races have a chance with. Sure it isn't the iconic thing, but we've had that since the start. The Allience really only have humans and that's about it, while the horde have a far more diverse group that get far more story in general.
I like the fact that Thrall was going to outright execute Garrosh then and there. I do have a feeling that the next dishonorable leader will be coming from the Alliance through Jaina.
Also, I like the "Awww sh**..." look from Varien when he first see's their choice of a warchief.
