Might be a stupid suggestion or thought about health system.

Why do fps games have fixed health system, where it should be based on a confidence and vigor system, so it should be calculated using that range to make it a bit more terrifying and strategic. I think it would be a great addition to where, if the player is stressed, his confidence and vigor score takes a hit, hence dying with less bullets, compared to one who is just ramboing, killing hostiles in streaks.

Would that make the development complicated? Definitely

But I imagine, people would be forced even further to question their positioning, since that would mean a direct loss to their HP or stop them from going all over the map.
