Maybe we can imagine for a next version a type of damage for each weapon just like there are damage type for magical damages (cold, fire etc...)
-Piercing (Swords, but also arrows etc...)
-Crush (Maces, flail)

So a Mace would have for ex. do 7 Crush while Sword would do a 7 Slash. An unarmored target would take 7 by both weapons while an armored one would maybe take 1/2 Slash damages and full Crush.

Of course it's impossible with actual system.
