I admit I was surprised that this is a thing. Pleasantly so as I'm so used to it being disabled nowadays, though I've yet to take advantage in spite of doing badly in so many fights.
We're on just one difficulty level in EA and more will come later, right? They could just disable combat saves on the Hard setting, and leave it for Easy and Normal mode. Or make it an option in a Settings menu..
I like the feature and was glad to see it, considering how long some of the fights are.
