The idea of divorcing labor from reward for an item is a core tenant of socialism They essentially don’t care how much work you put into getting said item, and instead determine its value for you. They in this instance would be IMC.
IMC wants the overall saturation to be greater for an item, so they modify a DKP value, which doesn’t care if you kill 95% of that value or 1%, they just are doing it for the “greater good” and not necessarily who worked harder for the item. The key tenant is that you have no hope of obtaining something if someone doesn’t do the work, it doesn’t have to be you. Where if it was RNG, only your effort would effect your reward, independent of other players.
What the DKP system does is encourage similar behavior to that of citizens in socialist governments. Such as the famine in China. You can farm more potatoes or rice, but you may only get 1/1000 of your effort back, if any at all. So most just let “someone else” do the work, and still tried to benefit from the reward.(they stood in the same food line, even though farmer A did 99% of the labor for a crop, he got the same payout as bum B who did nothing.)
Its the distribution that’s key.
