You are always arguing from both a meta perspective and an in-lore perspective. Choose one.

Yeah, that everyone know. But the real question here is "How"? If she had the power to subdue a god, why didn't she do something to defend her people?
Creation magic, hydaelyn was very specifically created to subdue. Zodiark was never intended to fight. Hydaelyn never had to keep the aether shroud active, that's a lot less power needed.

If Meteion functions as a "single mind", having one off the grid is a plot hole.
Meteion doesnt function as a single mind, there is a shared consciousness she can connect to.

So why it's in the main quest?
Because main story and side story happen in the same universe? What kind of dumb question is that, why wouldnt it be. Do you have the same grievance with the end of MSQ cutscenes in each expansion referencing the raid quest series?

It's the end of a story. It cannot have "I think" "my interpretation". It's over, we were supposed to be sure
But then you ask me about my interpretation anyway, so idk about that one chief, usually not everyone needs every thought spoonfed to them.

I don't care about bad stories. If they wanted to make a drama, do it the first time we arrived in Sharlayan, not after we were in a hurry to save the world.
But it's a very uplifting point in the story, giving your group the strength to weather to coming storm. It absolutely fits as encouraging send off to save the world. Urianger wasnt ready for it yet and Moenbryda's parents were also occupied. Again something you'd know if you had paid attention.

For real? I don't trust a bunch of teddy bears that say they terraformed the moon. Put someone charismatic but less silly and I'll take it seriously.
Well you can see they terraformed the moon so you dont have to just take their word for it.

Me answering your questions can only speak about how much attention you have cared to pay to the story, it cannot speak to how good or bad the story is. There are only tons of doubts if you dont care about the story and therefore dont pay attention. Something you seem rather open about, atleast you're honest about that.
