I think She's always required the agents, as well. There are many tales of heroes that had eldritch powers, did everything they could, and it still didn't work out. I feel like She'd intervene more if She could. And I suspect that Hydaelyn has a good reason to be wary of making beings of great power, or giving mortals immortality, or what have you. I wouldn't be surprised if She once tried it and it went bad. (Inb4 that's how the Twelve started and it led to the First Umbral Era.) I theorize that She's content to sit it out until the Ascians rock the boat, and then fires some Echo buckshot into the crowd only because She has to - and the welcome package for that job is really, really lacking. Though, hell, even Midgardsormr finds it impossible to keep track of what people know, don't know, and need to be told.
Also, I guess being mad at the Mother for being vague, reactionary, cautious, and then escalating right to throwing nukes in an emergency is about equal to being mad at Her for having realistic imperfections, being goddess of Light and life only incidentally, and not preventing the game from a plot.
It's odd that we agree so much on paragraph one and so little on paragraph two, lol.
Being that man (allegedly) came into being after the division, and has only lived, evolved, and thrived in this cosmos as it exists, I'm not sure we can "unring that bell" and survive with "the world we fought for" intact, if we survive at all. Elidibus would have us believe we'd be better for it, but I'm not so sure. I think Light and Dark must continue to exist, and I'm not sure that either can ever win. But is it too simple to assume that story arc ends with Zodiark existent but silenced and Hydaelyn willingly quiet from here on out as Her children thrive? What curveball is the game going to throw into that?
I have this nagging worry that if Hydaelyn is really the core of the planet, changing the core changes the planet.Can we say we won if we lose the world as we knew it? At least if She willingly goes quiet "in victory," the reins of history pass to man and we only have to kill the gods between.
But I completely disagree with you about Minfilia. She liked being one of Hydaelyn's chosen, she wanted to do her part to save the world, she labored to develop become stronger in the Echo and commune with Hydaelyn, and when Hydaelyn told her she was needed, she went willingly. Through her Hydaelyn spoke for a short while longer, history was nudged in a (hopefully) better direction, and Minfilia was happy for it. And when Hydaelyn had the power to release her essence as Emissary and send her to the First - even though Urianger basically orchestrated her exile from our world, she told everyone to forgive him because if he could have asked her, she would have volunteered. I think her consent makes a world of difference.
An alternative theory mistrusting of Hydaelyn should have persuasive answers for: Why, during the Astral Eras, when man was at their strongest, did she not reveal Herself and urge man to lay siege to every fragment of Dark in the known world? If mortals are Her children, couldn't She have made at least those entities without Darkness if She desired? Why is Darkness bound to the heart of man?
Granted, I think part of that answer is itself that Light cannot be Light without casting shadow in which the Dark can take root. Only in a world with neither Light nor Dark can we be free of that truth...and can mortals live in such a world? Should we want to?
Recently I've had this tingling beginning of a theory that mortal life IS Her defense, that we are Light and Darkness, that we keep the balance, that we live short, hard lives that inspire us towards cooperation and conflict - some act as if influenced by the Light, some act as if influenced by the Dark, but most of us just live, and there's nothing we won't do to keep living.
