Nope. That is not how ploot works. A player needs to be in physical proximity to the kill to have a RNG roll to get loot. In contrast, a player in an FFA game can wait in town and get all the leftover gear in your enigma example.
That isnot was is being asked for. Slippery slope/strawman
So if someone in some future time does ask for something potentially, that does not invalidate that is not what people in general want or being asked for. I have seen players who support FFA loot making threads about increased drop rates. Does that mean we should get rid of FFA loot? Of course not. Strawman/slippery slope
