Makes no sense that a player can't crawl with this, but can jump while crouching... For a combat-based game, I'm surprised that this feature is added. If you were sniping, you'd like to crawl while in position, not have to completely give up your position to move. Also, jumping while crouching in real life is impossible anyway, so the claim of "pros" is entirely defeated.
The run force, I'f anything, needs to be a bit more than default, but less than the current.
80 health is adequate.
