Delirium Drops: This isn't a bug, right? Can we get a buff?

I've done a good 20 delirium maps since patch all T13 to T15 and have found ONE drop above Greed rarity whereas prior to the patch I got a more or less consistent at least one above Greed. I just need one measly Fear or Suffering for an amulet, this is getting ridiculous. Not like I can focus Delirium so exclusively as to run them every map, either. Is rarity really that tied to drop amount? Or is that just another chance by virtue of another distillate? Because fogs end SOOOO friggen fast, especially if the map you are in doesn't allow for a more or less straight line in the fog's direction.

Same. Ires and Greeds.

I'd totally be ok with making maps delirious that the delirium mini bosses could drop higher rarity more or less consistently. Not like you get one every time.
