Gaia's Outfit on Mogstation

Same for the Garlean stuff. I'm not against it being there. But people insisting so much that they want it makes me wonder "why do you want something that's so associated to bad guys and genocidal maniacs so much? xD"

Let's just forget for a moment the fact that, as Joven already said, Garlemald just have cool armors.
People can like obvious villains factions for many reasons, it doesn't mean that they endorse their political ideology.
Garlemald were once underdogs born in a harsh environment who couldn't even manipulate aether in a world where it gives you a massive advantage. The fact they grew up to be a powerful nation is inspiring to some. And we met many Garlean characters who were reasonable or presented as sympathetic.
Classic Disney villains have been popular over the years for many similar reasons. They're the underdogs, they're usually the force working against the establishment, they're full of personality. For some, it makes them much more relatable and sympathetic than heroes, despite the brother killing and puppies skinning part. Our relationship with stories isn't rational and it isn't supposed to be.
