Adding more camera options to third person would be very useful for people with motion sickness. I have a friend who suffers from motion sickness and although third person helps... The over the shoulder camera still makes him sick. He has played other games where you could flip it from right shoulder to left shoulder view and it seems to help, but what he really needs is the option to put the camera behind the character. Having the character in the center helps ground him and gives him a focus point witch helps reduce his motion sickness.
I also got sick just watching a few minutes of gameplay between this and the strike bounce. I second this request. Third person option or the ability to distance yourself more (like in Satisfactory) would be helpful.
Do they have FOV settings? Have you tried seeing if it helps? That helped me a little in No Man's Sky (although the No Man's Drunk mod helped most because it removed the motion bounce). It might just be the strike bounce. It's super subtle in this game and you might not notice it unless you have this disability and are looking for it before buying.
