Crota's End World Record: 30'02"

Dayyyyuummm... From the poster: "We favor the left side and sit on the stairs and keep two back with Ice Breakers to kill mobs, and the other four mid stairs in a bubble (helm of saint-14 to blind any overzealous thralls). The four people in the bubble are me (sword guy) and three others with Gjallarhorn's equipped. Once I grab sword, they wait for me to go invisible and get beside Crota then I tell them to fire (3 gjallarhorn shots + others shooting) and I attack him. While I'm attacking him, they focus on mobs (especially the ones top left and top right with hive boomers). Repeat for two times each sword carry. After every two sword carries, ogres spawn, before ogres spawn we run into the bottom middle room to kill them, then rinse and repeat with swordbearer until Crota is dead. Also, make sure the person with Chalice ISN'T the sword carrier because they're most prone to die, and if you die with chalice, ogres come. Basically, play smart, and don't die."
