Where does this even come from? Is it a Warcraft thing? Orcs in Tolkien are different.
Yeah, likely. And if Blizzard wasn't the source (I think they lifted a lot of stuff from Warhammer, but I'm not especially well read on the subject) they at least propagated it.
The thread title, and the discussion, just reminded me of the game Of Orcs and Men (perhaps intentional from the OP?), where you play as an Orc warrior with a goblin sidekick against monstrous humans. Bit of a fresh air, at least thematically!
