Perhaps “one” piece of gear may drop at the mayhem level I’m farming at, M7 at the moment.
In other words, of everything that drops for me, when I check it all over, one high score item may be present. Quite often the one item is not a legendary and is useless for me.
This has been my experience for several weeks now and has led to many many duplicate useless items.
It’s easy to think that most battles result in one or perhaps two items for the mayhem level.
