Personally this is the most excitement I've felt since Wrath of the Lich King. Lore wise it is so much more interesting to me than Pandas or Cataclysm. But with that said I keep going over my head.... another Hellscream expansion? Couldn't they let it lay for a bit? Garrosh seems to be playing a major roll in the next expansion again..
Still though, the whole idea of going back to the roots and the real Orc oldschool feel about it, can't wait.
