Bit OP I have to admit xD But I have some suggestions.
Hold Time: In the inevitable config, have a hold time. This hold time represents the duration that the avatar can hold them for, so that then can't do it infinitely.
Air Particles: There's a lack of air particles. I can see the air particles, but they're very faint. I'd say increase them a bit. Not too much to where a view is obstructed, but a bit.
Mode of Escape: I used this on my test server so Idk how it interacts with players, but from what it looked like there isn't a mode of escape. I'd say, in an attempt to balance it out, add someway for players inside to battle the trap. Like if the player enters the avatar state inside the sphere, it breaks. If a Firebender or Airbender uses their burst abilities in the sphere, it temporarily collapses. Stuff like that. I know it sounds complicated but it's some ideas I thought of on the spot.
Sound: There are some really cool effects, but it'd be neat to hear some sounds to go along with it. Probably just the elemental sounds for each blast and some sort of "windy" sound while you are holding the trap.
Okay well, these are some of my suggestions. Now I'm going to say I love this move so that someone doesn't come on here accuse anyone of being hateful
I LOVE THE MOVE! I'll prove it in a rating
