This has me thinking... Maybe I missed it, did Orcs even have a name for their planet pre-Draenei?
If Ogres outlived the Orcs on the planet, why the hell do THEY call it Draenor? Its like me sailing to madagascar and naming it Humbug Island, and the natives are like "Sure we'll just go with that". Surely the Ogres have a different name for the planet since it was originally their planet.
