Rare drops percentage increase on certain maps

[rIVOLINO]

this is why this hypothetical counter would register the kill of the last boss within a period of time, it shouldn 't be fixed. as soon a map is not played much it 's counter should go up. I understand what you mean but the concept is simple, less played maps are harder to complete and that 's why they should have a better reward.
Would you rather do a fast run with less loot or a hard and possibly more fun run with more loot? That 's subjective maybe but I prefer the latter.
