I didn't exactly state that I explicitly wanted different damage types. I merely wish for weapons to have their own special abilities, perhaps even as a bonus vs different types of enemy armor ... or simply bonuses based on what type of armor you choose to wear. For instance, wearing leather/light armor could greatly increase the parry bonus of a short-sword or rapier.
As for blunt vs pierce, I merely think Axes, Hammers, Maces should somwhat ignore armor defense, while swords, spears, and arrows should somewhat ignore skill defense. The amount of skill defense a sword, spear, or arrow would ignore would be based upon the attacker's attack skill, perhaps combined with the quality of the weapon (or at least the "speed" of the weapon)- like how aerodynamic the arrow is, or how wieldy (light) the sword is. AKA mithil over Iron, or shortsword over longsword. Although longsword has the advantage of greater damage ....
say longsword could be 2-10, while a heavy axe is 1-12, a short sword is 3-8, and a hammer is 3-6 (but ignores armor more-so), while a mace is 1-8 (also ignores armor mor-so)
Im just saying we need a little variety in our weapons other than how much they increase the attack stat. Also, I think heavy armors should give a slight penalty to defense skill, while light armors give a bonus to defense skill, so there is some-what of a choice between High Armor, low skill defense, or Low Armor, high skill defense. High Skill would be good fighting against people wielding large "smash" weapons like hammers/mace, while High Armor would be a good protection against arrows/swords.
Shields would also be good against arrows, so there are always hybrids (shields are probably BEST strat vs arrows, or at least should be ... as well as shield based formations)
