People are talking about killing alternate timeless legion members such as KJ, but I was under the impression that demons like that are 'timeless' in that they exist everywhere, like old gods and such. I mean, The legion are smart, if there were multiple versions of themselves, wouldnt they just traverse these dark portals, team up with each other, then proceed to destroy each respective universe.
It sounds crazy reading it... arg. Help me out here. Same thing with Sargeras, is there another Sargeras in WoD somewhere?
