So it'd make the training even harder for them since their bodies are harder to be affected by the fel magic necessary for the DH training? Besides, I think saying that what the nightborne went through during their millennia of isolation makes them more resistant to mind-control and possession is a bit of a stretch, don't you think?
So now void elves have the whispers of the void
and the constant struggle against the demon inside? So being a demon hunter would be twice as difficult for them than it is for the night and blood elves.
Those are entirely uncorrelated.

Why? It's a process with a
one chance in five of surviving, and then you'll
still have a good chance of dying after surviving the training, either by the demon inside consuming you, or you taking your own life out of madness. "Because they would like to" simply does not cut it as a reason.
Except it is
not happening in our world anymore.
"Demon hunters have a constant craving for fel power and demonic flesh"
Not from you, apparently. Joke aside, yes. Reason is paramount. Nobody does something so unsafe and fatal like the demon hunter training without reason.

Pretty sure that's just a game mechanic to not make warlocks and shadow priests basically useless in that fight, since it'd force them to stop casting at all until the debuff has worn off.
