And again, another speculation about the warriors of darkness = old warriors of light

[Kallera]

... personally, I hope the Warriors of Darkness are just regular adventurers like us, roped into a conflict they don't understand and want no real part of, someone we could be friends with in other circumstances. Make there be no real differences between us except the god we're shackled to. (My dream of them being the lost Scions for maximum tragedy has been dashed, so...)

I like your personal idea a lot, actually.

Though I would like to point out that when there was wild speculation about what Dalamud was in 1.0, someone managed to hit the nail on the head with their speculaton. xD
