and how "big" this "faction"? especialy after dalaran turning neutral again? where are them? i only saw veressa on vindicar telling alleria "sylvanas bad, she with hordies", and before that on nightfallen rebelion. And this not exclude that if we see "high elves" playable we will see them as customisation option for BE too. And with golden eyes too.
you know what will happen then? "HORDE BIAS! WHY THEM GETTING BLUE EYES TOO! HIGH ELVES ONLY SERVE ALIANCE! AND GOLDEN EYES! ALIANCE WERE PALADINS ON THE FIRST PLACE! *roar*"
edit: you know. i now even want them to add HE for both horde and aliance. so i will see more aliance crybabies tears. And how lore will be twisted with explanation why part of High elves killing other High elves.
