The action begins. That's the long-awaited Toph: and the fandom is satisfied with the invincibility of the character, and there was no fight with Kuvira.
If Toph had taken out Kuvira, then the question would arise that Korra was not needed at all (if again others would have done everything for her). After all, it is necessary for the "avatar" to defeat the villain, otherwise it is not canonical.
Su's fight with Kuvira is the best thing that happened to Korra since the first season. Why can't we do more such spectacular fights and less "I'm an avatar, I can't help anyone:`(((".
@juliakey: In this regard, I did not have enough plot with Katarra. Or at least something similar. She's just a hermit somewhere in the South Pole region.
. The legend should stick to someone
