Eorzea has much Light? How?

[frostmagemari]

So I gather that the problem of the Eorzea now is there's too much Light. The Warrior of Light has been too heroic and the world faces destruction from imbalance.

However, the actions of the Warrior of Light have not been able to stop a World War from waging. Brutal repression, slavery, massive loss of life, endless war and attempted genocide from Warriors of Darkness from another world. This is the world with too much Light? Is the moral of the story that war and genocide are good things that bring the world into balance?

I shudder to think what plunging this into darkness would entail. The Warriors of Darkness tried to wipe out an entire world, mass genocide. How can the story follow in their footsteps? How can we darken the world when nearly everyone dying happened in the "world with too much light"? Am I missing something?

Honestly.. from everything of light and dark that i've seen, it seems like it isn't a conflict of Light and Dark. They use those words, but they don't mean anything. More than not it seems that there's a conflict between chaos and order; which is the theme of a lot of other FF conflicts.
It's just that it's easiest to display chaos and order by stopping/starting war.

So it's not that the world has too much light, but that the WoL is imposing too much order on the world. We are effectively putting an end to every conflict across every continent we come across, and as a byproduct, stopping everyone from making their own decisions because the WoL is telling people what the best end to every conflict is (or forcing it on them). If we eventually defeat the Ascians on our shard, the major force that tries to cause chaos in the world would be gone and the light would start to take over; just like if the Ascians defeated Hydalen's chosen, the largest force of order would be gone and darkness would start taking hold.
