Have blight league been shadow nerfed with drop blight maps(not blight maps)

have blight on maps as league content been nerfed(not blight maps)?
Ran on t14-t16 blight on maps with all nodes for increased drop cards for more than 30. Drop blight seemed to be cut. Am I having problems or is everyone like this?
Immune response didnt take cause weak dps, but last leagues i had a much more drop of this maps, bug or nerf, wth
