I would like the enemy equipment response to how I play so much more if reverting it wasn't limited to Combat Deployment missions. Whose idea was that?
MGS3 allowed you to sabotage enemy rations and ammo depots. That should have been a constant option within the open world. "I think I'm going to infiltrate and blow up their defensive equipment storage before I take on this mission". That would be a meaningful way to interact with 'side' content facilitated by an open world, much more than harvesting plants.
I'm more bummed by the lack of gore, to be honest. I would like to target specific body parts and I want legs to blow up when I hit them with my anti-material rifle. It's stupid that a soldier just gets bloody when you throw a grenade, mine or C4, too. I know it's a sick and petty thing to demand, but come on, you give me a thousand weapons to play with and there is virtually no difference between shooting with a shotgun and a machine gun? Hasn't Kojima watched Rambo IV?
