Bloodstains corresponding to blood lost (Visual cue for medical need/trust mechanism)

[Serrath 0]

This is part of an effort to help establish trust. I'm gonna say that bit up front.

Realism Junkies:

If you're going to say the word "realism" in your post, hold that thought and consider for a moment that most of the people reading this post understand how bloodstains actually work. The issue doesn't need to be brought up, we're all acknowledging right now that we understand how reality works. (If you're not sure, feel free to experiment with your arm, a white shirt, and a steak knife.)

The idea:

Add bloodstains to the player's body corresponding to how much blood they're missing. Someone with 10k-12k blood would be clean, 8k-10k would have a noticeable bloodstain on the front and back, 6k-8k would have multiple bloodstains, and below 6k, just throw a ton of blood all over them. As the player regains blood, bloodstains are removed. (Gasp! The anti-realism!)

The idea behind the idea:

You're hurt. You've got 4k blood. You're in a bit of a pinch. You need a blood transfusion. But! You've got a shiny AK with a few mags. You go around shouting for transfusions and you're gonna win a lifetime's supply of lead between your ears. With bloodstains, you can identify another player in dire straits and patch each other up. It's much easier to trust someone at low health, since they need the blood (and clearly an ally) more than they need your gear.

As an extra bonus, if you're travelling in a group, it's easier to see who needs medical attention.
