but that wouldn't happen Dark age of Tech  weapons were powerful enough that you could take out a star with a handgun, the fluff makes it all out to be as strong if not stronger than necron tech with the added addition of powerful psycher tech. Hard-Light cities and all are great but when you say your tech survived the fall "mostly" your opening a can of worms in which the logic of "why the fuck not" emerges. next thing you know your writing that grey knights have Vultron or that everyone in the galaxy gets a multilaser even tyranids.

Remember in the dark age of technology we have Skynet, deathstar handguns, the Thunder Warriors (aka we're about as good as if not better than a Ultramarine, for even those who predate the ultramarines wish they were one), and easy to mass produce titans. litterally the only thing the Dark Age of Technology does not out gun the current verse in is psycher levels...but even then they were the ones to make all the orriginal anti-psycher tech. mayhaps the DAoT needs a retcon so humanity at that point doesn't make even the eldar look like cavemen but they do.
