Then put it into words that actually carry the meaning of what you are saying?
The ENTIRE argument you are basing this on is that mythic geared raiders have lost the concept (knowledge) of how need before greed loot systems work. My counter is these mythic raiders use a need before greed loot system in their mythic raids, so how could they lose the concept (knowledge) of need before greed loot systems if they use it in their weekly guild/pug runs? It really isn’t hard logic to follow unless you just don’t want to admit your entire argument has 0 basis in fact.
