Thought of another adjustment that would be nice to see, even if it only provides benefits for a few niche situations.
Empty Main-Hand - It would be nice to have the ability to equip nothing in our main hand and equip a weapon in our off-hand. Now, I know you're thinking "what purpose would this serve", but it would allow for Monks to be able to wield a weapon in their off-hand (one that immediately comes to mind is the
Club of Hill Giant Strength
) while keeping their main-hand empty in order to be able to use their Action to make Unarmed Attacks and benefit from anything boosting those attacks (items, Tavern Brawler feat, etc).
Alternatively,
Ability to make Unarmed Attacks even when Wielding a Melee Weapon = Would be a nice alternative that would solve the situation created by the above being disallowed. Monks could wield the above-mentioned weapon and still choose to make only Unarmed Attacks.
