Yeah, to be honest, I don't support shipping. On top of that Katara is my least favorite character.
She's bossy, overconfident, and they sped up her learning curve for waterbending way too quickly post-North Pole.
She couldn't do the water whip worth a crap when she got the scroll, and ever since seeing Master Paku apparently everything just comes easy to her. It's a design flaw I don't think anyone's pointed out. The worst climax of this was in the Puppetmaster, where she literally gets -zero- training into the bloodbending technique, and is suddenly able to do it in the brief time it's used on her, Sokka and Aang. Absolutely stupid.
I was so happy when Toph put her in her place in the Runaway.
