I think the attack on Theramore will have really, really dire consequences for us Hordies. We have that non-aggression pact with them since Proudmoore died and Thrall has respected that for years. Now good ol' retarded Garrosh just goes and attacks the one place he should NOT have touched, like, ever. I expected the whole Alliance to rise in anger and Jaina joining the fight, Thrall going berserk on Garrosh and who knows what else will happen. Maybe not even orcs will get to pay the price.. imagine Darkspear trolls get attacked in retaliation? Taurens? Can you imagine what Vol'jin and Baine would do? the Horde as a whole could be further shattered thanks to Garrosh and his complete lack of vision and responsability. Even Jaina could become badass and hate Thrall for it, because he couldn't keep his little dog on a leash. I expect this to be the start of something really huge. Add to that all the territory that Alliance lost during Cataclysm and you have massive hatred just waiting to come out and get sweet revenge. Just look at what our dear Zarhym wrote on his twitter account:

"If you wanna make an omelette, you gotta break Theramore"

it's just the first step towards massive, all out war. I could not be more excited for this x-pac, it has incredible potential and I think we'll have a blast!!!
