I don't know, it's something I'm hoping will get answered during Early Access since as far as I'm aware no one's mentioned anything about it.
Well, you could also be like me: Old "hardcore" player turned half-casual that got really tired of the harder-is-more-fun-and-challenging shenanigans.
I was there in the 90's with the Eye of the Beholder games and similar, and Arena and Daggerfall, and Baldur's Gate, etc. Getting older I just don't have the patience nor see the fun in games like Dark Souls that just come off as overdone on the "challenging" aspect.
My philosophy is as long as you're having a good time that's all that matters. If that is the case for you, then it is perfectly fine. Super crazy difficult mode? No thanks. But enough to keep my mind engaged, to keep me from being able to auto pilot? Yes please! Again, this is just me. Personally finding out that a 7 year old was able to succeed in easy mode puts me off, but then those young buggers are smart these days.
I am going to try nightmare difficulty, ff off, and will adjust as needed.
