Eh, I feel some of your arguments for WoW similarities are kind of weak, saying the Granok are like orcs is strange to me because just being a big burly battle-loving race is not enough to make the 'orc clones', especially since they lack some of the orcs other notable traits like the honor-obsession and demon hangups. I might as well say the Granok are klingons. They share about as many similarities.
There are a few similarities here and there between the games but I think that's less due to any intentional design aspects and more due to certain things regularly being present in the MMO and Fantasy genres.
