So, I'll keep it brief, you used to get knocked out at critically low hp even by gun, I propose the return of being knocked out by fists, bats, hammers and all other blunt items
The reasons speak for themselves, boxing rp which is picking up and beatings, dont know how doable this is after the changes being made but I feel like its more than plausible.
Edit*
After seeing Canadians response regarding the old systems poor optimisation causing lag, I'd suggest that blunt weapons and fists force a /fallover after crossing a certain damage threshold
