Sylvanas goes to Hela's domain and has some hard decisions to make, ends up meeting the uncorrupted golden Val'kyr in Odyn's realm. Cue redemption arc that sees her taking this Warchief gig seriously.
Alliance-side, Jaina ventures to Hela's realm and is confronted with Arthas's tormented spirit, who is convinced she's just another twisted mockery of his loved ones (prior to this, we see a shade of Uther as a DK mocking him for his weakness in not mastering Frostmourne or something, IDK. Something to establish that this is what Arthas is tortured with for his crimes in life and undeath). Cue heroic BSOD as she realizes how far down the rabbit hole she's slid and finally establishing herself as a pro-Alliance character who isn't rabidly anti-Horde.
That, or Blizz takes the easy way out and they end up raid bosses. Could go either way.
Be seeing you guys on Bloodsail Buccaneers NA!

Jaina right now.
Welp, now that we have a full on cinematic and all that shit. We can safely assume that the theory is 100% wrong. Now that we know that blanazzar killed tirion, and gul'dan obliterated varian, we can also safely assume that sylvanas won't change factions anytime soon, and that...well...hordies are pussies, even though the say that they have excuses. Hey, I know vol'jin didn't do jack-shit, but atleast give him an honorable death. All he got was a stab wound, and died from some whack poison. VARIAN 1 SHOTTED A FEL REAVER! Tirion was burnt alive but the fuck-boy krosus, and was tortured by fucking balnazzar. However, vol'jin got stabbed. LOL! That's not a good way to end one of your most badass troll characters.
I'm sorry horde, but you pussied out. If I were garrosh, i'd bomb the ToS, like I did with theramore.
