If they had known they were going to get 52 episodes from the beginning, what do you think would change?

They don't necessarily have to be good changes, just what do you think would have changed?

I still think they would have done the seasonal approach, I think they said that was the plan just to be different than the original, and I think that's good. Amon or any of the villains really don't feel like they could carry an entire series.

I think we would have gotten more characters introduced that would eventually become airbenders. Some more focus on the air acolytes who became airbenders.

Either less focus on Republic City, or they would have switched to make the other seasons set there; probably the former.

I feel like Unalaq, Desna, and Eska would have been in Book One coming to help Korra; maybe Zaofu as well so they don't come out of nowhere.

I do think they would have taken time with Mako and Korra instead of getting them together so fast, so they probably would have been endgame.

I also think season one and season two would have thirteen episodes each lol.
