What's the point with that quite lackluster story in Endwalker?

[Skyborne]

I used to be really interested in the Twelve and thought that surely there was some amazing backstory on them and their creation. I was excited when I heard that the Alliance Raid would tell us all about them. What I've taken away from that trailer though, is that they're just primals. Probably dreamed up by the early sundered as they crawled around with their stone tools trying to figure things like wheels and fire out.

I could be wrong, of course, and I'd be thrilled if there was actually an amazing twist behind their origin, but that was what my first impressions were and that made the prospect of them much less exciting for me. Guess we'll see soon why we actually need to kill the "gods".

Here's my dumb "theory": the Twelve are just toy puppet-constructs made by Hydaelyn based off the memories of the 12 who became her magical skinsuit in order to teach the cavemen sundered how to human. They were placed back into their toybox soon after, but something went wrong and they are awake, I guess. There will probably be nothing about the Convocation's early attempts to work with humanity, as Emet said in 5.0. The 'epilogue of the Hydaelyn and Hydaelyn and Hydaelyn and also guest starring Zodiark from Devil May Cry I guess saga' part has me pessismistic, though I'm sure I will be wrong and I will consume my shortpants.

Anyway, while Nald'Thal's design looks super cool and I love how the god of crafting's halo is made of nails, I'm not a fan of the idea of just running through a gauntlet of the Eorzean pantheon that has been in the background of the lore for a decade and casually just slaughtering them one-by-one before heading back home for burgers and coffee.
