sundered doctrine is probably one of the most miserable experiences to do in flawless solo

I just want that dang exotic turret rifle, and trying to do the dungeon flawless solo for the triumphs so I can get a better exotic drop rate is so infuriating, the stasis and strand psions are insufferable, the damn explosive worm husks, and having to do that 1st encounter again and again and again and again is driving me up the walls, I spent 4 hours trying to the 1st encounter without dying and I kept on failing, and it's miserable.
