I guess if you want to take it all back to Armageddon, yet ignore the lore Games Workshop made back then at the same time, that's fine.

Just don't act like its not being added because it's false, it won't be added because it is too imbalanced / Different from mainstream.

Thing is, it's not "Lore", it was one piece of fluff written from the perspective of an Imperial Techno-Magus. It has also never been repeated in any other piece of background from that point on.

It's not meant to be taken as a serious explanation, just another example of the backwards thinking of the Ad-Mech.

To see people further extend it to imply Orks don't run out of ammo until they think they've run out of ammo just hurts my everything.
