I just can't understand this point of view. Nothing is being taken from the Horde at all. High Elves aren't in the Horde. Why would the Horde deserve to crap all over logic and lore in the current game to take an Alliance race? I don't get it.
Shen'dralar has allied with Darnassus. Dark Iron Dwarves, being ruled now by Moira have joined with their Dwarven brethren.
I heard the same whining about Horde getting Blood Elves in BC. "Horde get a rehashed... blah blah blah" but that all worked out fine didn't it?
