Teriz denied Demon Hunter because all his counterpoints were real. We all just didn't expect Blizzard to completely redesign demonology to make them work.
But they did, so Teriz was right in that they'd have to, he just incorrectly assumed Blizzard wouldn't do that.
For all we know, they could completely change Unholy Death Knight to create a Necromancer class.
