Hmmmmm either way sounds good to me honestly. I'm not sure if its a big problem since I haven't seen a lot of people doing it yet, its just when that one guy finds out he can do it and sticks to nothing but doing that. Also there is one flaw with your sword design that I found in one of your other mods.
If the sword is not moving to fast, the other player can grab your sword by the blade and not have to worry about taking any damage. Not sure if you intended for it to work like this, but I guess the video did say that some swords were blunt edged so it can be considered fair in a way.
