I think that over time your character should start regenerating blood over time. I googled it and it said that the human body can make about a pint of blood every 24 hours. I think you should regenerate 100 blood per every 20 mins playtime. This doesn't have to be exact but i just wanted to put something out there. If you dont regenerate blood i think you should be able to give yourself blood with a blood bag. Its hard for solo players like myself to get blood unless you find a friendly player who is willing to give u a blood transfusion and not kill you. I think solo players should be able to use blood bags on themselves even if you don't get the full amount of blood as you do when someone else gives it to you. Maybe every blood bag that you use on your self gives you 3000 blood instead of full. But a blood transfusion by another player will still give you full blood.
