I personally like the challenge balance in hard mode but it encourages stealth/not getting in enemy's faces. The gun fights will be more challenging. But if you want to feel flashy and powerful, hard mode may not be best.
This sounds exactly how I want it to play in hard mode. I'm not one for going into games with a gung-ho attitude flashing my guns about. I like the challenge of a tougher enemy and playing the game as it was meant to be played. I don't want dumbed down enemies who are just there as a hindrance more so than a challenge. Thanks mate.
