I got to thinking, refs are always in the way and get too close to the action. It's less intimidating when you know another man is there to help you out of the fight What we need are drones. A little drone flying about high above the action won't get in the way and make the fighters feel more trapped. Also you can put a camera on the drone for super close action. Drones can have little yellow and red card arms extend out if needed and make loud noises depending on what's needed Drone: "STOP HITTING THAT MAN YOU HAVE WON" etc Thoughts?
