I don't like the realism philosophy at all. I can only carry so many weapons and ammo cause it's realistic, and in the same game I can get hit dead on by a shotgun, and as long as I manage to crawl behind something and sit still for a few seconds I'm fine.
I would enjoy more weapons being carried, opens up a few more options in a fight beyond "Grab rifle, get shotgun, gernades, go." But if people are going to defend this under the banner of realism, explain how regenerating limbs are realistic. I get that having limited health would be suicide in current gen fps, but either make an excuse for the regeneration, or use something else.
