Oh Kay... MC still being a bitc|-|ing fanatic and gush over some 2 bit characters. Really, those dudes couldn't even stand against pinky of Lucifer... let alone the presence. And let's not forget, with spirit bending and blood bending in full Avatar mode, MC could wreck most of the JL senior member.
Why Join them for what reason. They are simply being immature and trying to prove they can handle more. Mc seems to be another I want to be a hero. Master yourself and control your fate. At the very least, be able to protect yourself before rushing to do so for others. Telepathy has no protection. Strength is just human. Perception is just human. Adaption capabilities are pathetic. Aero kinase expert but useless as he has zero situational training (scenarios and what to do). Zero psychology knowledge, detective knowledge or team training. Right, let's jump right in. Pure bs and plot armour. Watch some cautious hero, then come back.
The airbender, the more their detachment from the earthly world, the more powerful they are in airbending, while the more attached you are to the earthly world (money, bisios, etc.), the less powerful they are to the point of not being able to use airbending but they can use objects. as a channeler (hand fan) as it happened to the mother of the kyoshi avatar (Money) and apparently to kyoshi herself perhaps because her main element is earth as it is the opposite of air so the earth controls the more attached you are to the more powerful earth are more powerful are the earthbenders.
