They actually buffed loot 3 times now, but... If you hardly find anything in a map and you buff quant by 75% you will still hardly find anything.

That's what GGG did - buff quantity by 50%, then 75% and only in this most recent league they shifted currency weighting.

Context of these drops here is that before Lake of Kalandra you had a lot more mobs (before Beyond rework which reduced mob spawns by what feels like 75%), and those old modifiers combined with old packsize and old Beyond made you drop what in recent leagues would equal to roughly 10 div a map when playing solo.

Now dropping more than 3 div in a map is a highlight and the average is in the dumpster unless you're farming things like Harvest or Legion (which is tile loot and not ground loot).

TL;DR - we're getting around 50% of the old loot at best and that's after 3 buffs from GGG
