Im a fan of the Old Horde, and i would like to come back in WoD given the lore that will be in the expansion, even though i dont like the current Horde at all and neither the Alliance. Its hard for a lore player to play in a faction that he doesnt like.
But i would like to ask you something guys.
Do you think after Alliance defeat the Fel Horde would have been marching against the Legion?
Some say that Gul'dan was just a pawn, but i dont think so.
He was power hungry but i think that if he could, he would go on to destroy the Legion and their masters, and with the Eye of Sargeras in his hand that would be the next step.

From 2:00 to 2:30.
But you think that Gul'dan with Eye of Sargeras, Fel Grom Hellscream and with armies of Fel Orcs, Ogres and Amani Trolls could have destroyed the Legion?
What common Legion soldier could have taken on the common fel orc soldier (which is known to have tremendous strength)?
