Stamina/Mobility overhaul would be good for harder difficulties allot of people I see seem to take no issue with carrying a 23-28 pound Machine gun and most often the HTI .50 BMG 19.9 pounds (with no optic or suppressor) I don't think there is a member of the SOF community that doesn't understand the value of weight savings they are ounce counters as they know all to well how ounces turn into pounds, and pounds turn into pain. One can push thru pain but they can't get around the hit to mobility & efficiency that carrying too much would have on them.

So let those that don't know better carry too much but penalize them within an inch of their life, and make their mobility/stamina extremely low so they learn they can't bring everything and a kitchen sink with them. Beat them over the head with there poor choices, don't reward them.
