I would love to be a firebender! Or an airbender..I find both of those amazing.
The reason why most people wouldn't want to be a firebender (I suppose) is how fire is destructive. You can't control it like water or earth..or air. Once you bend it, it spreads. Oh well, I still would love to be a firebender like Zuko and his grandson General Iroh II~ xD <3
