I just straight up ignored the “Vengeance or Renewal” due to its sheer absurdity due to… Several reasons, both in-and-out of universe.
However, I do think there’s been a lot of misinterpretation of Elune’s role in the burning of Teldrassil. Elune as an entity has kinda had her hype built up to massive amounts. However, she’s never been omnipotent, omniscient, or known to directly intervene in catastrophic events, such as the War of the Ancients, the Third War, or the Third Invasion of the Burning Legion (i.e. Legion). Frankly, to me… I’ve always thought she was powerful, but never omnipotent. It’s a fairly-common practice in real-life religions for gods to be powerful, but non-omnipotent, to be limited to acting within their domains. Not always, but not uncommon.
I think Elune has historically been the psychopomp for the kaldorei. She’s guided their souls to whatever afterlife/afterlives they might typically go to, which does not necessarily seem to be the Shadowlands (could be wrong!). Thinking of the souls we have seen, very few are actually kaldorei, save the ones rescued from the Maw.
Point is, as has been demonstrated, Elune was incapable of stopping Teldrassil. Why? I’m not sure, power levels in WoW have historically made no sense. At the same time, she was asked to assist Ardenweald by her sister. Remember that sad cinematic of all the wild seeds dying? That’s what Elune was trying to help stop. So, she made the best of a bad situation and, instead of sending the souls where they might otherwise normally go (one of her afterlives?), she instead directed them to Ardenweald. How did she not know about the Maw? Because the Winter Queen didn’t know at the time of the request to inform her. The Winter Queen didn’t learn about the souls going to the Maw until the Maw Walker told her (because the Eternal Ones are incompetent). And, Ardenweald isn’t necessarily a bad afterlife for a Kaldorei. Maybe not ideal, but that might be alright, especially if it’s just temporary.
That’s my interpretation. However, my bigger problem is that this took information jumbled over three years to make sense. It’s really frustrating to try to piece together what happened, because Blizzard insists on their wait-and-see trickle-feed method of storytelling, where everything is kept hidden to be revealed later. Even stuff no sane person would keep hidden, things like what is this character even doing? They do it to drum up hype and get speculation videos to advertise their game for free, not because they care about telling a good story.
EDIT: I guess my point is… I don’t like the new cinematic, but I also don’t hate it. I’m at that new standard of indifference to anything Blizzard churns out. So, I’m not saying it’s good by any means. I just want to dislike it for the right reasons: it’s another sloppy beat delivered far too late to have an impact, not because Elune crapped on the Kaldorei.
