Sorry, I thought my OP was very clear.
Current: a weapon with the Versatile property is a one-handed weapon that does increased damage when used as a two-handed weapon.
Theorycraft: a weapon with the Versatile property is a two-handed weapon that does reduced damage when used as a one-handed weapon.
What do you believe is better about doing it in reverse?
