It would appear that players are no longer able to restore a deleted Demon Hunter if there is already another Demon Hunter on the same realm. Something that has been possible since Legion launched, and has been known to Blizzard for almost three years, has been quietly ‘fixed’.
Honestly, why wait till now?
So a bug was fixed?
Yes and no. It was reported to CS a while ago, and was possible as recently as April this year, with a CS agent even confirming that the cap was only on CREATING new Demon Hunters, not restoring old ones.

LOL! I could just imagine your Demon Hunter saying, " I have sacrificed everything. What have you given?" 
So they fixed a bug. Got it.
It was just a bug they weren’t going to punish you for exploiting.
CS reps aren’t devs; they can only describe the game as it is, not as it was intended to be, unless the devs specifically tell them something is a bug.
Indeed, though Blizzard has known about this for almost three years, why change it now?
Low priority bugs are typically only fixed when its convenient. Maybe it was finally convenient.
Blizzard Devs to CS reps.
Also, what’s going to happen to all the players who already have multiple demon hunters on one realm? Surely if this was unintended and could be exploited, they should have to transfer their characters or delete them until they only have one, if Blizzard are indeed enforcing the server limit.
Honestly Legion is over. Who cares if someone has more then one DH(I did not even care then.) This is something I will not be shocked to see removed as soon as 9.0.
They fixed a bug that allowed for more demon hunters? Am I missing something? I’m not seeing a downside.
except if you could restore em and have multiple DH on same realm that would bypass the reason for only allowing 1 DH a realm 
The downside is that it’s a change that’s come for an issue Blizzard has known about for almost three years. If it is exploitative as some have said, they surely should have fixed it sooner. If it isn’t, then why fix it this late? It doesn’t make sense.
i mean Legion had content and BFA not so much so they have free time this xpac 
Legion has been over. They should just get rid of the 1 DH per server requirement.
But I thought there was only 1 demon hunter allowed per realm. If someone creates more, that’s an exploit. It’d be different if you could just create more, but you had to go through the steps of deleting your character, making another, and having them restore the deleted character to get around it.
I’m trying to understand why you care when they decided to fix it.
Well hope the other requirement does not get looked at.
You need a 70+ to make one, but not to have one.
He lost the character he deleted.
