Let's not kid ourselves: The Morningstar is basically just the Mace but on a different weapon slot, though I can see the appeal of having a weapon that has identical stats to a pre-existing weapon. In the morningstar's case, you're moving the Slot 2 mace to Slot 1.
I think it'd be worth it to have two weapons of similar redundancy for Guardians and Men-at-Arms to use as Slot 2 cut weapons:
Flyssa: Identical to 1h Sword stats-wise, but is a Slot 2 weapon for Men-at-Arms and Guardians
Khopesh: Slot 2 Falchion for Men-at-Arms (dunno if it'd be too busted for Guardians tho)
