It's ironic that some of the things that I mentioned actually become real in Natlan. My point is that some of Natlan's technology make sense if we connect it to Pyro, like Mavuika's bike who runs with combustion engine, and also jetpack, since it's like a rocket, it use combustion hence why it spit out flame. Or actually any machines or vehicles because they can run with combustion engines/combustion based propulsion.
It's a miss opportunity to think that they have done correctly in regards to connecting Natlan's technology to their element (Pyro), I think the devs want to do that. But the problem come when they make it a tribal or traditional based nation.
If the devs were to make Natlan with industrial or technological theme much like Fontaine, it would be a lot easier and such technology would not have caused such controversies.
So the conclusion is that they did right in connecting the technology to their element (Pyro), it make sense. But they kind of made a mistake by making it a tribal-themed nation.
