A thing i have been noticing for a while with stamina, is how it's been overly punishing in some areas, but not nearly as punishing in others. It currently makes quite a few regular-ish height moves difficult, without being able to stop a lot of the very crabby runny stuff. Same goes to weapons, some movements with close hands take a lot less stamina than they realistically should, meanwhile what should take the least force to do(moving weapons with your hands far apart or moving light weapons with center of mass close to your hands) takes a lot more. For that i have two suggestions:
For arms
- Make stamina depletion affected by how close the weapon's center of mass is to your hand(the closest hand to the center of mass in the case of two handing a weapon).
A smooth gradient from what we currently have if the hand is far from the center of mass, and about half depletion if your hand is on the center of mass.
Optionally, having a bonus reduction in depletion for having your hands far apart would also help make more structured swings feel more natural and less tiring to perform.
This would still prevent crazy one handed big sword swinging, holding dane axes by the base and spinning them, and so on, without being overly punishing to the kind of movements that should take the least force to perform, like swinging a kilij or properly wielding a bardiche with your hands far enough apart.
For legs
- Check the height on your hips when compared to your lowest point (likely your feet), and have the stamina use be related to it.
A range from half depletion if you are at a standing height, to double depletion if your hips are near touching the ground.
This would much more naturally discourage crouch running, but still maintain crouching stances that dont move a lot as a viable defensive pose, as well as keep a more normal stance for most combat, as people would be standing more to take advantage of the better stamina.
