No, this adds to the tension. I once broke my leg, killed the fucker who broke it and crawled for almost an hour to cherno, found some meds. Then got shot... :) Keep blood as it is, is only annoying for people who either suck or dont plan ahead, it is so easy so kill a cow and get 8 meats and thats almost 8k blood, if it regened then finding a knife/matches/hatchet would be pointless KEEP BLOOD AS IT IS!!!1
