I see that they have real weapons, they are simply not sharp, yet still can do huge damage. Single landed strike during battle rush on an unprotected part of body can cripple the fighter. If this is allowed, than why not fight with real knifed and blades are not allowed?
Hard to see whether Medieval MMA will officially be a sport that we can bet on. If you'd watched a single battle on the youtube link given, some of them struggle to even pick up the weapon, one has a hard time getting up. You got to see how they come up with this but this is purely just for their entertainment. More like just a cosplay these days where we see teens wearing Mobile Legends costume.
