But why would anyone use arming sword over sabre in this idea? Arming sword gives nothing, yet with Sabre both str and dex fighters can use it at it's best.
Dex is a better stat than str. Hence str needs a boost in combat. That is more damage from weapons that are not finesse.
how about;
Sword(arming), 1handed, 1d10 Slashing, 1d12 versatile,
Rapier, 1handed, finesse, 1d8 Piercing
Sabre, 1handed, finesse, 1d8 Piercing
Sword(short), 1handed, light, 1d8 piercing,
Scimitar, 1handed, light, finesse, 1d6 slashing,
Smallsword, 1handed, light finesse, 1d6 piercing,
Longsword, 2handed, 2d6 slashing,
Greatsword, 2handed, heavy, 2d8 slashing,
Elven courtblade, 2handed, finesse, 1d12 slashing
