Same with highmountain and taurens. See, draenei going draenei and tauren going taurens is something that makes kinda sense. Elves whos being given to some elves but not all elves is something else entirely.
And just to say this, AotL and we are joined forces against one enemy. The other 2 would be done as a race if we weren't there. The LF Draenei have been in that war for millennias.
