In short:
Occasionally, clouds of fractured Light gathered and gave shape to beings of far greater power, of far greater potential. Among these were the naaru, benevolent creatures composed of scintillating holy energies. When they gazed out across the immeasurable universe, they saw a realm of limitless possibilities. The naaru vowed to use their mastery over holy magic to spread hope and nurture life wherever they could find it.
The naaru have vowed to bring peace and hope to all mortal civilizations and waylay the dark forces of the Void that seek to engulf creation.
The story does not tell to whom they vowed. Or why. To me it seemed like a gamble of their kind, that they saw something worth preserving while other forces, like the Legion, saught to twist or destroy. And they payed a huge price for that, with most forces of the Light being destroyed by the time frame of Legion.
Reconstruction stories can be good or bad. Just like any methods to tell a story could be good or bad.
Example of a “hero” story done right IMO:
There is no corellation between following this concept and story having to be bad. Just like outright switching the horde leader and the concept of W3 horde to Garrosh / Sylvanas direction and focus on them does not make the story of the horde automatically more diverse, interesting, and “better”.
Scarlets are not naaru, and the difference between a regular mortal user and them was mentioned before.
Plus, story of Scarlets was any decent only early on. I’ve read recently the comic written by C. Golden. The one about that undead inkeeper / ex-Scarlet. And you know what motivation she gave to them? A kid asks his sister, why did she kill a blood elf and a forsaken. And the answer was “Because!”
That’s it. No deep reasoning, no exploration, no nothing. They are bad, so having revenge against them is fine, forcing them into undeath, torturing, performing surgery experiments while keeping conscious, and eradicating them no matter old or young is good and you’re not supposed to question it, or wonder if it could go differently, here or in another timeline.
Is this the depth that could be called something good or interesting? Not to me, but hey, different people like different things.
There was an old comment about various forms of Light practices:
is holy of prists and paladin is same energy?
Both priests and paladins can wield the Holy Light. However, not all wield it through the same means (e.g., Elune, An’she)
So the end product (Holy Light spells, etc) is the same, just the philosophy that masters it different?
I think for game-related reasons, yes. Examples that come to mind are night elf priests and tauren paladins.

So, no.
No, you just can take a look at the story of Mereldar. [actually I am not quite sure what “no / yes” means in the beginning of a sentence. What I mean is that the idea of what I say is not quite what you suggested, sorry if it was confusing]
“The Seven Kingdoms” (In-game book):
…
Though each of the city-states became prosperous in its own right, the empire of Arathor had effectively disintegrated. As each nation developed its own customs and beliefs, they became increasingly segregated from one another. King Thoradin’s vision of a unified humanity had faded at last.
And among all of that what was the original story of the alliance (although this story predates the game events by a lot), with backstabbing, prejudices, internal struggles, etc., is where the ideas of the Curch of Holy Light formed. And the idea behind it was kind of the same as draenei and naaru: you have flawed characters with a lot of less than good motivations and ideas, and a force that slightly nudges them in a direction away from fully succumbing to 100% negative, sometimes successfully sometimes not.
They should’ve been. But the current narrative team placed it right next to the original WoW-W3 vision of the horde.
Actually, to think about it, all that I wrote is actually more me thinking about what could a different story team make out of the foundations of WoW lore.
I think you are correct that the current team would not do much better regardless if the warp naaru, or keep a mockery of what they were in the story.
