Enough with Garrosh and Grom. I just want to see a new main enemy in wow that is not Horde based (and I play mainly alliance characters). I think its time to see a second coming of the Shen'dralar in the next or final expansion. A truly neutral race for the longest time that gets thirsty for arcane magic again and causes some sort of rift that brings the burning legion back. Horde leaders, though they are traditionally thought of as the "bad guys" have had way too much screen time in recent expansions. If not for Jaina crying constantly during wrath we would have forgot she was there.
Just think about it, a neutral race going rogue and causing the end of the world.

Did we ever see the elder Saurfang actually die? I think he would be a great asset to the horde and could actually go a long way in an end of the world fight to combine horde and alliance forces for the "final fight". He has Varians respect as well as Jaina so getting the rest of the alliance to fall in line behind him would be a no brainer.
