Hmmm. But about those that already exist? Don’t you think they should be allowed to come back to their people, once Sylvanas is defeated and the manipulation of the Jailer revealed?
In Legion we see that the Dark Rangers work side by side with living Blood and Night lives in the Hunters hall.
Even if we can assume that many/all of them loved Sylvanas and answered directly to her, she’s been gone a while now, so they may want to return to their people. Or do you think they should be outcasted, like the original Undead folks were which lead to the birth of their faction?
As for the matter of them being hunters only, that’s a fair point, but I keep wondering why when Blizzard announced Night Warrior eyes for all night elves that feature was welcome, despite the fact that in the lore it only belonged to ONE character (Tyrande) of ONE class (Priest, High Priestess even!).
I mean heck, at least we know there were ‘numbers’ of Dark Rangers in service.
And adding the customization to the Blood Elves rather than to the Undead is just a matter of logic, to avoid a duplicate.
Let me elaborate, taking the Death Knights as an example: they are also undead, and yet they are flagged with the original race name, and they have the same racial skills, too!
So a Dark Ranger could possibly work at its best as a special class.
However, we already have a Hunters class which includes them (Legion class hall) AND it would be annoying to have ANOTHER elf only class.
Which leaves us with the option to add a whole new race model to the Undead (unlikely, unless we want to give them models for all races) or just give the Blood Elves the customization shrugging off the class only coherency as it was already done with the Night Warrior eyes for the Night Elves, and the undead detail as it was already done with the Death Knights.
And also if you think of the amount of work involved to add a new race or a new class as a feature… I ‘d say ’Dark Ranger’ is either going to be a customization for the Blood Elves (and possibly Night Elves) or it just won’t happen.
