Idk I gess Id be an Earth bender because its incredibly convenient at all times...well most time. Pless you can bend metal if you have enough koo points.
If not that, then its all air from there.
AWWWWwhh Yahhhhhh
I would be a waterbender because mostly they are more spiritual other than the airbenders. Also, they can control ice, snow, and water, and mist which is really cool. Also not all earthbenders bend metal, it's only Toph. And I don't like fire; I'm not that aggressive and Air; just isn't as cool.
I would bend earth because i can be hard headed sometimes and i really like the technique they use. I would also work on it long enough so i could learn to bend metal like toph did. Also im not as free as an airbender, not as wordly spritual as an waterbender and i just don't have that fury for firebending.
