last couple times I went in and had 3 randoms in Tier 3 unstable/heroic and the screebs spawned for the 2 Scorn bosses... not even close to beating it.. cause they cast that invincible totem/charm thing and the screebs that you need to explode to break their shields are now invincible and invincibly exploding in your face... ...it didn't used to be this way even a few months ago.. but they tweaked it and now if that is the heroic/unstable.. you need.. basically all focused on defending from screebs... at least 2 wells..etc too bad because I used to be able to farm for the impossible RNG waking vigil and vouchsafe that I want (no way to target farm) and you get 2 drops of Dreaming City weapons if you can get there. Tier 2 is much easier and I think you get only 1.. its more assured. At least the Dreaming City World Weapons as a whole are still better than other worlds but could use the same update stat/perk/enhance that all psedo-sunset weapons need.
