okay so people are like "air bending is rlly powerful cause you can bend anything" and I'm just like "no. That's not how it works."
Air bending is controlling the winds, you think the wind can bend metal and pull water from the plants and pull the ground up from under you? Last time I checked, it couldn't.
The real reason air bending is really powerful is cause you can't see it, dummy. You can't see the wind, only feel it's force and see it's effects on things around it, like a black hole.
