I finally did it yesterday with a team of me, my brother, and a friend who isn't super good at the game, but plays a strong team game. Setup was: Me: Defender Titan, Colovance's Duty, Invective, Harrowed Elulim's Frenzy Brother: Stormcaller Warlock, Harrowed Doom of Chelcis, 1000 Yard Stare, Harrowed Quillim's Terminus Friend: Nightstalker Hunter, Finnala's Peril, Stillpiercer, Harrowed Elulim's Frenzy Defender's Suppression Grenades help limit Taken abilities (the thing that makes them most obnoxious). And Bubble helps keep everyone safe, I used Blessing instead of Weapons as survival was paramount to damage. Stormtrance helps crowd control, great for Boss room clearing. Landfall is also great for blinding enemies and not letting them use abilities. Shadowshot grants big damage on boss man, and also good for clearing the rooms before in a faster manner. Try to limit the enemies in the Boss room before doing damage to the boss otherwise you may find yourself overrun and dying frequently. Tl;Dr: This is all super obvious shit, but it may help someone in their team-building or something.
