So I can make CaS of unique rpg characters from my games and play them in fighters. At least for me personally.So the main reason to have an unarmed figher is so you can make a CAS of an existing character that is known to fight barehanded ? Not really the strongest justification. Unarmed combat can be simulated by just using the grab and kick button, and certain characters have punches and shoulder strikes. You are only limited to your imagination. Like if you're not talking about competitive gameplay, then you're 100% free to already simulate weaponless combat in the existing system. You can pick Nightmare and spam K 6K, 4KK.. and both sides will be happy.
One reason why the boxing gloves as a creation part was so universally reviled was because it was out-of-place (not only chronologically, but because it was a hand protection in a weapon based figher).
