Orcs, Humans, Draenei and Highmountain Tauren should have DH options at least. All 4 have a legacy of fighting demons. Draenei have been doing it for over 30,000 years. Orcs and Humans have been doing it for generations. Highmountain Tauren have been doing it since the days of Huln Highmountain. All 4 have some form of "Fel" appearances. All that's needed is tattoo, skin and color options.
But what ever, not going to happen.
