Exactly as firstblood said, during normal gameplay rather then just kifefight to get bonus hp per knifekill, I said 55 hp and believe it would be great to cap it at 100 hp. Meaning that per knife kill you get bonus 55 hp but your hp can never exceed 100. Would add a new dimension to the gungame and I believe it would placate all the "Knife only" people if they knew they could get their HP back by knifing the gunman. Plus it would just be tons of fun

but as first blood said the most important decision would be how much HP you should get per knife, I used 45 or 55 as that is what I'm used to seeing, but of course we always have to fine tune it for our specific playerbase a more moderate 20-30 would be prefect as well
