<p>I think the rules would be rather similar to firebending, though headshots would probably be OK. I'd imagine sustained air shields would be restricted, as would air enhanced movements (i.e. no 40 foot jumps, no air scooters, etc.). Considering air attacks (realistically) aren't visible to the human eye unless it is acting on something, there might need to be a way to make such attacks visible so people could viably dodge or block air blasts as they could other bending attacks. Smoke, maybe? </p>

<p>That smoke ideas interesting, I hadn't thought of that problem. But instead, maybe the water below the ring generates steam and then other people could see the match because smoke is too thick </p>

<p>Air benders are peaceful people and i don't think they would want to be in pro bending. Tenzin did seem to enjoy it but i doubt they will be included.  </p>

<p>Yes, but as a sport to practice bending... </p>

Do you think Air ball would return. We saw it in the first few episodes of ATLA
