I like how in Avatar it’s basically random on who gets it, also it’s a checkbox. There aren’t people who are just STRONGER at bending in a “they have the pure blood.”
Toph is a strong bender but it’s shown to be due to hard work. Aang is kind of mid as a bender, but can use all 4 and no one has fought an airbender in living memory so that’s his advantage.
Also bending is cool, but not all powerful, you can still get punched.
