I say all that to show that all the little problems I'm talking about in AtLA are fundamentally the same as the big problems in tLoK, which most would agree with as being weaknesses of the show.
The nonbender issue was just as big in AtLA as it was in tLoK. It's not an "issue" because it isn't honestly engaged with by the show, but benders are clearly more capable in combat than a nonbender could ever hope to be. And it's really illustrated best thus: any bender could conceivably learn Ty Lee's style, whereas she could never learn how to bend elements. Ever. That's the largest difference. What is the most impressive feat Ty Lee ever accomplished? Knocking out Katara in close combat?
I don't think I've ever heard anyone go "Why is Sokka so competent? He should suck since he's not a bender."
I'd say Ty Lee's most impressive trick was her defeating an entire earth bending army squad by herself.
And it's not a dishonest engagement because fights don't work out based on whose 'potentially' stronger. Yeah, a bender can learn Ty Lee's style, but who has the time to master their bending art AND chakra points to the extent that Ty Lee did? Keep in mind that Azula and her teammates are the most competent people in their field, practicing their specific art through childhood. Notice how everyone in real life is perfectly capable of mastering a multiple martial arts, but most people don't even know a single one?
The kind of warrior your talking about would be extraordinarily rare at best, and can still be beaten through superior skill in 1 area, an environmental or strategic disadvantage, or just plain luck.
Three benders stormed the Earth Kingdom single handedly. Took out an entire army in a few minutes. The AtLA finale itself is a strong bit of evidence in just how out of depth a nonbender is in a bender's world. Every idea Sokka has is driven by the capability of Toph. Piadao knocks out a guy while Jeong Jeong lights up five town blocks and every tank nestled within them.
That's...really more because they have main character powers. In case you haven't noticed, those benders were up against benders + machinery. Jeong Jeong in particular was powered by the commit yet able to take out dozens of equally powered firebenders who have weaponized enhancements. By your logic, Jeong Jeong should have been annihilated, because the army has numbers and equipment and superior positioning going for them. If we had stayed with Piando longer, we'd have seen him cut down every mook in the entire city.
We all look the other way because it's honestly not that big of a deal and bending is cool, but any time the show acknowledges this disparity is cringeworthy.
You're exaggerating. If the show wanted to show nonbenders decimating armies of benders, they could, like they did with Ty Lee.
And it's obvious that by function of the show are they two different things but it makes little sense to demarcate the two, seeing as they're both relying on the wisdom of past lives and engaging with them. Which is the entire point of the Avatar.
I always understood it to be channeling the wills of the past avatars. Why would the knowledge of how to move water repeated 1000 times be more effective at moving water than 20? The concept is simple, it's the force of strength that would be lacking.
