We are already punished by way longer dungeon run. Now loot too? So now we have to pray when queuing DF, load have mercy on me and give me 3 players who will be at their il cap, and skip all the cut scene and running the state of the art computer so not a extra second of loading time.
Then if we set a range of time with different rating, we have to consider il vary between players, potato computer and new player watching cut scene and at the end, the speed run make no difference from now
