It’s endlessly funny to me that Orks are among the most brutal, caste-system based, martial strength = legitimate authority, but they are powered by feels.
A Eldar or Guardsman would look at a typical Shoota or Mek built by Orks see a series of parts assembled to a facsimile of the intended device - but it is the Ork’s belief that it will work, that makes it work. In a future where the Imperium will invade whole systems over rumors of ancient human technology that is superior to their creations, Orks pop up from spores and can bullshit themselves to overcome physical laws.
Yep, as a fictional concept they are fascinating. They're less of a nation or a race, but more like an invading self contained ecosystem that makes supply lines obsolete. Their technology is so ridiculous that it's almost useless in other species hands, but they can pillage their enemies weapons to their own advantage. Their entire species social class structure is based on merit, biggest ork is DA BOSS, because it's biologically baked into them.
