I feel like Arcstrider's melee would be thematically and visually better if you used a dagger/knife to attack instead of your fists/knuckles (the weapon kind of knuckles, not normal knuckles lol). It just doesn't seem very "arcstrider" to brute force the enemies with your fists, the subclass's lore is all about balance and flowing and the fist doesn't really fit that in my opinion. It seems more likely that an arcstrider would channel their magic through a weapon when attacking rather than just punching everything, especially a subclass built around mobility. The punch doesn't seem very fitting to hunter as a whole either. A dagger is much quicker, quieter, and more damaging than your fists, and hunter as a class is about being quick and deadly. Thanks for reading, have a nice day/night :)
