Looking at the High King definition on wowpedia:
It doesn't really sound like a king - subjects relationship, and it's completely opposite of Warchief - the Horde relationship, which is unquestioning obedience. I don't even know where did you get the part about the warchief. The warchief is THE leader of all who belong to the Horde. That's why everyone obeyed Sylvanas, even if they didn't like it. That's why Saurfang was deemed a traitor. That's why Garrosh could simply forbid the usage of plague by Sylvanas (that she did is another story).Originally Posted by Wowpedia
He is a king to other races same way as the Queen of England is a queen to you (if you're not english), but she's not YOUR queen.
But yeah, if you can provide something that can disprove what Blizz devs have to say about this, go ahead and do.
