My rng is fairly decent, I usually get exotics to drop around 17 completions. It’s happened to me numerous times. For Finality’s Auger I’ve only completed the dungeon solo 4 times. FA dropped for me on my third run, then I got the catalyst and my solo flawless completion on my fourth run. I did however, spend a lot of time practicing each encounter and completing the catalyst quest. It seems like the drop rates have increased or in my experience at least, doing a solo run without leaving the activity has boosted my chances of getting the exotic. I got Icebreaker on my 6th completion, a solo run which I was not expecting haha Plus now I only need to do Sundered Doctrine on master and with clan mates to get the seal. I’m not sure why this is the case but it’s been a far more enjoyable experience than the other dungeons.
