Right. Elune can be Primary: Life; Secondary: Arcane. Putting it together is Astral.
As for her role as a psychopomp and that stuff with Xe’ra? Yeah. Bit of a stretch, but Blizzard’s never been too rigid in their lines between magic types, so I don’t see why we should start here.
Right, I’ve seen that quote many-a-time, but… “true goddess” means nothing. It has no definition to it other than, “not similar to other powerful entities at the time of writing”, for example the Wild Gods or the Old Gods. I’m just not putting a lot of weight into the word “goddess” or the phrase “true goddess”. It’s too vaguely defined to have a meaning worth discussing.
Myself? TL;DR: Yes, I’d be fine with that, but I know other night elf fans that disagree.
Again “real god-hood” is, and always has been, nebulous at best. It doesn’t have any concrete meaning, so… It’s not really worth discussing at length.
“Reduced in power” is, again, weird. I don’t want her to be weak or weakened, but I don’t think she needs to be a universe-spanning, creation deity. If she was kept at her original description of “Azeroth’s moon goddess”, with the power that entails, then I’d be fine. She can guide and protect souls, she can shoot stars at bad guys, she can make constellations, she can make you into a stronk emo if you throw an orc head in one of her moonwells while listening to Evanescence. Great stuff, feels like it “fits”, and that’s good enough. Would I be pissed if we just strolled up and raid bossed her one day? Or within one patch of meeting her she gets her butt handed to her by the baddy of the week (or, worst yet, Anduin going through his own stronk emo phase)? Crabsolutely. So, she doesn’t have to be an unbeatable fix-all, but I also don’t want her being the cosmic equivalent of the Worf Effect or secretly evil. And there’s power-scaling and narrative middle ground there, which is where she has kinda rested for most of her existence in the Warcraft story. If that’s the “”“power equivalent”"" of the Winter Queen, Denathrius, the Titans? Fine with me.
I don’t care about Elune in-and-of herself, right? Like, I don’t play an Elune, I play a night elf. My relation to her is through the night elves. From a story-standpoint, she is an extension of the night elves. She is one part of their overall design and appeal. She’s a massive part, a part so big that I can’t imagine the night elves sans Elune, but still… Just a part. So, to me personally, my emotional connection to Elune is her role for the night elves, which has, thus far, been “mother moon”, and a mother should care about her children, and care deeply. Otherwise, the entire foundation of kaldorei society would be built on what amounts to be in-universe baseless speculation. You’d uproot their culture and undermine some of their most core principles.
One of the worst things Shadowlands has done is answer questions no one asked or wanted to know the answer to. Before Shadowlands, had anyone ever asked, “Gee, are the kaldorei important to Elune?” No, because we knew the answer: a resounding yes. Of course they are. Elune and the night elves have gone hand-in-hand for almost twenty years. Why change that? Who wanted that changed? Who wanted that challenged? No one, least of all night elf fans. Everyone else gains basically nothing from it, and night elves actively lose because of it.
So yes, I’d prevent Elune from taking additional power ups if it guaranteed that the Kaldorei remained important to her.
