It doesn't fit in this topic, as this is about the faction arnor and not armor.
But yes, we are already using about 10-15 different types of armor.
F.e.:
slash = dealt by swordsmen
specialist = dealt by pikemen
pierce = dealt by archers
knight = dealt by knights
crush = dealt when crushing enemies with knights/ents
siege = dealt by siege weapons
and so on.^^
