Tainted (Corrupted) Currency

The tainted currency in POE 1 was a godsend, often high level items get corrupted and the person simply forgets the cheapest part of the craft... Quality, if you search the market place there are countless mirror tier items that simply forgot to add quality.

Please add some sort of tainted currency to the game so we can add quality to our corrupted items. I'm sure the community will want this as it's a very bummer feeling nailing the perfect corrupted mod, extra socket etc. and making a simple error of forgetting to add quality.

Make it super rare, only drop on corrupted maps, anything but please include it for us. I hope the community is behind me on this one. Let GGG know we would love some tainted currency drops!
