There is a similarity when comparing both the ATLA and LOK. It is a story of the individual who is different when comparing to the past Avatar and how they have to cope with the obstacle on their own, when the guidance of the past Avatar isn't always the best for them, more like the reference of what an Avatar could be.
Aang is a little kid and become the last Airbender, not knowing how a kid will able to save the world. He is still considered a naive boy in the start of the show. Long enough, he learns how to be mature for a young age. The comic shows more of his challenge of being a young Avatar. This may sound like a typical story and most people may think it is not sound that exciting in paper, but damn the show done everything perfectly.
When comparing to Korra, she can be considered a tough but not quiet matured Avatar even though she already is quite impressive in mastering the elements. She's like the spoiled brat who hasn't yet to learn what to do or not do when making decisions and very vulnerable when coping with her consequences and experience, just like how a teenage girl usually does. Plus, as being the next Avatar after Aang, with how the world is quite different than it used to, it is understandable that she hasn't yet know what obstacle she has to face.
This is what similar about Aang and Korra, their challenge is different but as a kid or family show, they kind of doing their job right. So when looking at how Korra and Asami holding hands, let's just say how that's what young females do. Sometimes they want the time with their own and Mako and Bolin may considered best friend, but they are not girls like them. The focus of the whole LOK is how Korra, as a girl, a vulnerable one at that, learn from her experience to become much better, and Asami can be the best support and reflection for her. This can also be applied for Kuvira who is also a female and have the same reflection with Korra.
I write this to make sure that the SHIPPING is kinda pointless, even by the show writer's standard, because there are no more Legend Of Korra, maybe there's potential for the comic to be publish, and the conclusion maybe come from there. But, we'll have to wait of course. If there is another Avatar show, I wonder what he or she be like. If there is one, hoping for a more ruthless Avatar that can consider difficult to be noble. Just show a different kind of story, because I don't remember the requirement to be an Avatar as a good person.
