Farming Dungeons Sucks

Farmed the 2nd encounter of Ghosts of the Deep 90 times for about 9 hours straight. Was trying to get the rocket to drop with Envious and Bait and only got 6 rockets to drop. Farming dungeon encounters, especially old dungeons that are only on rotation for a week is atrocious with no focusing or red borders. Warlord’s Ruin is just as bad if you’re going for the Indebted Kindness. There should be double drops or a spoils chest or something for old dungeons, especially because of how hard it is to even get people to farm them. Thoughts??
