I love that Horde ending, loved the Alliance one too but I'm a wee biased being mostly Horde-sided with my characters. Really loved Vol'jin in this expansion and it was awesome to see him made Warchief but as that was apparently the Alliance version to the cinematic that I had previously seen, it was a little bit of a *plop* 'alright, new warchief' and that was it. There was just too little there to really make the change of leadership exciting for me.
But then seeing the Horde version and knowing an actual two minute, on the spot meeting that actually had all the racial leaders agree in tandem to the decision happened while the Alliance were watching from afar, that made it awesome. Vol'jin has rarely acted on impulse and he's always been on the modest side, seeing others closest to him as better candidates but never shying away when asked of him. He understands Thrall's choice and honors it, honors what it means, the request, not command to become the new warchief. I could probably go on and on about him like seriously

While some characters have fallen from grace, others are rising taller and prouder.
I'm REALLY wondering what Sylvanas is gonna get up to now..... All she did was pretty much do a long nod motion. Even Gallywix took his hat off and showed his respects but all she did was droop her head. Vol'jin won't take shit I'm sure so she's really gotta watch her back and not abuse his leniency, if he has any for her. And if the Alliance want to cleanse Hillsbrad and Gilneas, well, that's Forsaken territory. How's she going to react to that? How is Ivar and Crowly going to respond to returning to their home with the Forsaken literally free to wander just on the other side of the wall? She's just supposed to lie down and roll over (no ironic pun intended) while they do that and let unrest between Gilneans/Alliance and Forsaken boil over? I think we might see her getting up to some in-incognito plotting to keep that from happening...
