A moment if I could to offer conjecture on the topic. If we all agree (and it seems we do) that Saline versus Blood clearly shows an imbalance....why don't we just suggest to balance it instead? What I mean to say is, lets swap say, the values of blood regenerated on the two sources. Instead of Saline giving back 100%, why don't we instead just swap the values and make Saline give 20%, and actual blood give 100%? This way, its possible to stablize a patient from gun wounds on the fly with saline, but if you really want to give yourself and your people a chance, keep some blood on hand. That being said, I don't know if there is a limit to the longevity and effectiveness of blood kept in your inventory. If there is, great, it means the new values are proving their effectiveness in my offered implementation. If not, it still balances things out and I would suggest to implement a time limit to the blood and/or perhaps make its durability last longer by keeping it in certain portable containers, etc. Thoughts?
