Wrathion's plan is either a) "The Horde invading last time resulted in the creation of the Alliance, so a Super-Horde should then make the Alliance and (prime-)Horde unite!", b) "Fuck the lot of you, imma go get my own army! With Blackjack! And Hookers!", or c) Whichever of a) or b) ends up working.More than anything I am curious as to how this fits into Wrathion's plans to unite Azeroth...why an alternate timeline Draenor of 35 years ago? For those of you who haven't completed the cloak quest, the very last step is actually to defeat Garrosh in SoO after you have completed your cloak and then return to him with the news and what happens after Garrosh's defeat. Basically he is furious that Varian doesn't destroy the Horde completely when he had the chance.
What is it, other than more, betterer-orcs that would serve this end? Hopefully it isn't just lolwowloreamirite?
Of course he's forgetting the secret weapons of both the Alliance & Horde - an elite group of murderhobos willing to do anything for shinies and happy to be pointed in a direction and be told "kill everything over there up to and including the scenery".
(i.e. the players).
