I'm just railing against the belief that it's OK for Hydaelyn to seemingly have possessed Minfilia for whatever reason. It goes against my creed to just accept this, especially as a Dark Knight; I fight not at the behest of the goddess, but because I choose to. (Well, technically everyone does, but I've faced the aspect of myself and acknowledged that I can leave it behind if I so choose). However, to have possessed the body of our dear friend, willingly or otherwise, should certainly paint Hydaelyn in a light she hasn't been seen in before, yet people are justifying it due to Hydaelyn's weakness and the supposed direness of the situation.
Necessary? ... perhaps. Perhaps not.
Either way, that's not the behavior of a benevolent goddess, and it sends a lot of worrying and bad messages. "Free will should be relinquished at the behest of the divine" is the big one that I take issue with here, since that appears to be what's happened. I don't buy into that at all. There are other things I'd say on the matter, but I'm too tired right now to fully articulate it all, so perhaps later.
