No naaru has did anything similar, ever. No naaru has created a race. No naaru has birthed a race. While, using the power of the Light, naaru helped shaped a race, this is not shaping by turning something into something else but rather a more mental shaping. Otherwise, they could have fixed the Broken draenei. Which they did not.
So, Elune is stronger then naaru. Furthermore, we saw Elune can ressurect the dead (Ashenvale satyr) and we saw proof of her curing corruption easily (same satyr). We saw that naaru can't ressurect the dead (crusader Bridenbraid in Icecrown) nor can they cure corruption (same crusader). They can only help guide souls into the Light.
Furthermore, many of the powers granted by Elune are stellar based. Starfall, Star shards, etc. No naaru have stellar type powers.
Furthermore, a naaru is a mass of crystals that uses the teachings of the Light. Cenarius, the son of Elune, has a stag part from his father and... a humanoid part which can only come from his mother. Furthermore, if Elune was a naaru, why doesn't Cenarius use Light powers and why didn't he teach the night elves about the Light, instead teaching them about druidism? It makes no sense whatsoever.
I understand where Blizzard was hinting through Velen, but if they stated Elune is a naaru they'd wreck some parts of already established lore.
Furthermore, as I understood, the Shao-Hao came after the spirits in Pandaria. So they were there before him. That said, he might ascend to become a naaru, I don't know how naaru are birthed.
That said, the night elf and the tauren both held Elune in high regard. In patch 5.1 as Horde you go and steal a bell from Darnassus. If I remember correct those sentinels are the only night elf encampment that's actually larger and night elf only. So maybe Elune just hinted the night elves and tauren they should get this artifact instead. Night elves just got to it first. And sent it to Darnassus.
