eldar orks and humans are 3 iterations of the old ones working with ways to tap into the immaterial

the eldar do not have genuine faith, they know their gods exist and revere them, but that's not a belief, it's a knowledge, everything they do is ritualised but underneath it all everything is consciously rationalised, as a race they're very attuned to conscious immaterial manipulation and almost that kind of manipulation alone
but one could say that without genuine faith, they're no real masters of their own destinies and instead have a fatalistic outlook to their existence

orks are a polar opposite, there's barely anything conscious about it, they do stuff because they believe it works, not because they know it works, so much so that you could say they don't have a real understanding of the difference between a belief and an info, they're designed to subconsciously tap into the immaterial and get a very specific result
but without proper conscious effort the orks too are locked into a cycle or a spiral

and then come humans, a perhaps lucky hit of the sweetspot between conscious free will and ability to chart a goal, and a dose of that good old zealous ignorance that in warhammer can literally help in achieving the impossible by believing hard enough


I am definitely reading too much into the accidental fluff accumulated over the years, but it's a functional headcanon for me
