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

[Lauront]

You’re the one that is constantly grasping at straws, constantly trying to defend your crystal mom waifu when for all intents and purposes, she is a monster. You are entitled to your opinion as much as anyone else is, however i have given numerous examples, backed by actual in game knowledge and lore to support my
claims. Your claims have constantly been “because the story says so she’s a hero blah blah don’t think too hard about it.” Fact is, at the end of the day, she didn’t tell anyone what she knew. She kept it a secret and it led to her destroying her own entire world. I’d rather not continue this conversation though as you seem to be getting rather tired of being proven wrong time and time again, and so i bid you adieu~

For someone who claims to understand the lore well, the poster doesn't even do that particularly well:






Dynamis does not factor into their solution because said solution is designed without knowledge of the underlying cause, instead being designed to buffer the celestial currents where they are weak. Nowhere is it attributed solely to Hermes (as opposed to scholars, in the plural, as per the source), nor is an understanding of dynamis mentioned as relevant - for all we know they could've simply inferred the pattern in question, with Zodiark able to bolster it as required. And I am not familiar of any sources that attribute Zodiark to him specifically.
