The only one that exists was from 2016. It’s 2020. Which again goes along with what I said:
DeVoid hunters?
Because the name “Azrael” is most likely already taken, so it would be without purpose! 
cause void-elves came-about after illidan stopped training dh?
Honey I know what he said. I can try to find it but it isn’t high on my priority list.
I just told you. It’s from four years ago. Which is why I re-quoted what I said.
I mean sure we have pandaren dk’s now…
the sky isnt the limit anymore…
what’s next DH goblins/pandarens?
Do you think that is the only interview he’s ever given? The only time that question was asked? Again, I can try to find it but it isn’t high on my priority list, I’ll see about hunting it down if I think about it when I have the time.
And it would have shown up in a search if it existed. If you want to prove me wrong, then by all means. But thus far, there is only one mention from four years ago. And that still doesn’t mean anything for the point I made. Which you keep ignoring.
Lightforged deathknights.
Anyone can die and be raised. There is no lore against that. Paladins died and became Death Knights.
Whatever makes this game sexier, I’m telling you if we went full Game of Thrones around here there would be a lot more people playing.
(Response): I believe it would be as simple as Illidan ruling that due to the threat of the Legion he’d be willing to expand on which races he’d be willing to teach.
(Aside): I really do enjoy how some of these Mechagnomes “operate” on these forums
Pretty much this. But the only problem is that the Legion isn’t a threat. The Argus world-soul, which was feeding their regeneration was destroyed, Sargeras is imprisoned and their “big two” leaders, Kil’jaeden and Archimonde, are canonically dead.
The Legion right now is a bunch of random demons, with no notable champions or leaders to rally behind. They’re about as much a threat as Kobolds are.
because not even the illidari wants these made-out elves
(Statement): During Legion this would be true, and I do believe they were training new Demon Hunters in the Demon Hunter class hall, though whether they were of other races, I do not know. Either way it seems like the easiest races to adapt would be Void Elves and Nightborne, though plenty of other races could fit in easily.
(Commentary): Thank you!
No, technically they - as a different racial set apart from Blood Elves - were not. There is however, a path toward this that could be lore-supported as I look at again:
You could posit that Blood Elf DHs were a group providing security for Umbric’s researchers and were converted during the ambush by Durzaan. Two issues though; first - they have never been seen anywhere in the unlock chain or in the world, and second - if they were there as a security team they should have been executed for gross negligence.
The demon hunters we play as are the illidari. They were created by Illidan long before the void elves existed. In fact as a group they are basically the complete opposite.
Umbric explains to us that after the sunwell went boom, and the population started siphoning magic to survive he and his crew quietly got further into their study of shadow.
The illidari blood elves on the other hand came from those who followed Kael’thas to outland, siphoned the most volotile of magics, and eventually pledged themselves entirely to Illidan.
Your point was pointless and thus worthy of ignore.
Editing: here you go.
“What about other races for Demon Hunters in the future? Anything is possible. The lore dictates that only Elves can be Demon Hunters and they went back and forth on it for a while. For anyone who had a picture of a Demon Hunter in your mind, you think of Illidan. So they wanted to deliver on that fantasy. For the future…Demon Hunters could instruct other races in their rituals…but that would be something to consider for the future.”
Yes. That’s the interview from four years ago that I already mentioned. The only one that exists. Nice try.
Explaining to you how they would have to implement new DHs, based off their current storyline, the fact that they added DKs in a similar manner and based off the fact that nothing has been said in four years, is pointless? 

No, you just have absolutely no way to argue against it and will ignore it instead. And since you can’t come up with an actual argument or any real points to make, I’m done.
