he knows Zuko is the Fire Lord’s son, settling Fire Nation people on Earth Kingdom land, and Aang wants to know why.

That's a really good point, but since Aang's thinking it, I suspect it's not supposed to be. The fact remains that Zuko is Fire Nation royal, creating a settlement on Earth Kingdom land, with at least a partial Fire Nation population. That setup has over a century of precedent for being a Very Bad Thing, and Zuko should both know that and take steps to reassure the local Earth Kingdom officials that he won't encroach on their territory or usurp their authority. He should probably at least consider having an Earth Kingdom co-leader, if not accept an Earth Kingdomer to have authority over him.

Embers!Yangchen needed to be saved from her own people and then her “friends,” by the fic’s own admission, dragged her into a war that got her killed. It hardly seems to fit with the Yangchen who was considered one of the greatest of all Avatars in canon, does it?

Yyyyyeah, Embers!Yangchen comes off as the "victim Avatar". While Kyoshi is the "merciless Avatar", and a female Water Tribe Avatar was apparently the start of the decline of the healers and a future one will be a guaranteed disaster, it feels almost... misogynistic? The male Avatars aren't good, either, but they usually have more agency or don't abuse their power, they're just mediocre.
