nd then you jump into a game, and a handful of Ork Boyz will gun your marine down in a hail of dakka.
In their defense you cannot use the bulk of the armies for the majority of the factions, They don't let you use their lowest tiers most of the time.
THAT and the game has a huge tendency to write in both myth and actuality interchangeably... As well as not splitting between "Heroic example" and "typical example"
Or rather reading 40k is absolutely terrible because you can't trust anything is true at anytime.

Mind you what I said doesn't apply to the LATEST version where they finally just went "Fudge it!" and completely threw the power curve out the window... then stomped the power curve... then lit it on fire... then stomped it again... then threw it into a blender. So now the game is entirely arbitrary to the lore.
it'd be ridiculously imbalanced in an actual game, so there's more than a little power scaling applied in practice.
It reminds me of the Halo lore.
If you actually read the lore then Masterchief is completely broken of a character and it makes a LOT of his feats seem really odd in retrospect (For example Plasma grenades? Can't hurt Master Chief to my knowledge) as well even the terrible weapons in the game end up having some sort of ridiculous super science behind it. (Yeah you think flipping a tank was odd? Yeah MC can actually do that)
And just like them both the games came first. I have NO idea why as a creator you would want to completely contradict your story and gameplay on purpose.
