In reading this thread, I thought of, what I consider, to be a reasonable compromise... A 1.5H weapon skill...
1H sword for short swords and rapiers.
2H sword for greatswords (even if very rare in.Glorantha/bronze age)
And 1.5H for those that can switch easily between both.
Agreed.
Personally, I'd make it:-
Dagger
Spear
Sword/axe/mace (club)
Javelin/sling/bow
1 Shield
So, similar, but slightly different. Dagger, Spear (probably as Secondary Melee), Primary melee, Primary Missile, Shield.
