What I find strange is the difference of power from hard to madness.
I'm able to farm hard on auto while leveling two gunner characters, possessed rockets (level 86) with primordials and corrupt droid (level 74) with eternals, plus DDE and Ibuki, and without getting a scratch.

I've only ran madness once, and with was on auto, with DDE, Ibuki, Osiris and Prisoner, and the team really struggled for the win, DDE dying in two different waves.

Anyone seen any primordial dropping?
