Resistance vs penetration

You know, it was awesome back in legacy, when you had armor values and you knew for a fact that this kev was going to take 2 m4 headshots rather than 1, because kev was the strongest armor. But in the new rust, your bolt headshot JUST might do 2 dmg to his facemask, or you might 1 shot him because you shot him in the eye by complete luck. I want a static value, I really want my battles not to come down to luck, And along with this, it would fix the pipe shotgun, which happens to do a whopping 1-5 dmg to a guy wearing roadsign armor. RETURN RESISTANCE!!
