So far so good with the development but I noticed a glaring issue that needs to be resolved:
Taking hits in combat should not drain stamina (the only chance you have at actually defending yourself from the next hit.) More often than not it results in you standing there, sword down like a blithering moron while the other guy hammers on you at will… I tell you from practicing martial arts that the most motivating factor to block a hit was being struck by the previous one. You are trying to design a “realistic” game and I am telling you now, if the guy is still physically able to lift a sword (no cut tendon, massive hydraulic decompression ect) then taking a hit is going to ensure that he has every motivation to lift his sword to defend against the next strike.
So I suggest a change. Taking hits doesn’t kill stamina. Swinging hurts stamina. Parrying/blocking hurts stamina less so (which is the truth.) This not only makes the combat more plausible but actually eliminates the current mechanic “if you get hit, even on your armor, with a training sword you might as well give up because you physically cannot defend yourself after the fact.”
