Have been running Duality every week since it released. The amount of armor drops is very, very high to a frustrating degree. It took three runs of Duality for me to get my first weapon drop. To this date (about 10~ runs in) I have not gotten a single drop of Stormchaser, and not a single one of the 10 deepsights I need. From talking with friends, the deepsight situation is the same with them. At this rate I should expect to get my craftable Epicurean or decent Stormchaser in 2023, and that is completely untenable. Armor drops are far too common, and deepsight drops are far too rare. I would very much recommend to weight the loot drops more towards weapons, and also make it guaranteed to get at least one Deepsight Opulent weapon upon completing the dungeon every week.
