Zutara vs. Kataang
Do you wish Zuko had joined the gaang sooner? That way we'd get more time with him and everyone and also more time with him and Katara and them getting close and developing feelings for each other. And also him being best friends with Sokka, being an older brother figure for Aang and Toph.. I really wished he joined sooner so we could've gotten more of this stuff.
