I think they should make it were the A.I responds to the flashlight if they are in the field of view of the light. They have confirmed that listen mode will be completely be off on this difficulty. They could remove the hud so if you get injured the player wouldn't know how much health is lost which gives the player a decision: save the rare med-kits or to use it for your wounds. (It may have been a big one who knows). Well that's just some of my ideas though.
