Hive Gland Farm

I want to do the herald stacker for my last build of the league, currently at 3/5 rings (had 16 rings so far...) but glands feel like the drop rate is nerfed since first couple of weeks.

I setup an Atoll in Eagon so can blast upto a breach in seconds, and whilst I see the blood isnt reduced, does the cursed map modifier reduce gland drop chance?
