So I just got into a Cradle of Shadows run and my group could not beat the guy who has shades and wraiths pop up around him making him invincible so you have to kill the adds first etc. I'm okay with that mechanic, but when the wraiths popped up (blue clear guys) channeling into the boss, they seriously had to be killed in 2 seconds (literally) or the boss one-shotted the tank every time. Not that one opinion makes a difference, but unless I'm mistaken (wasn't watching, was trying to DPS wraiths), the tank is incapacitated so they are unable to use any defensive abilities to stave off that amount of damage. I don't think there should be any one-shot mechanics at all, but maybe I'm just being a baby about it. Either that or remove the DLC dungeons from the random queues.
I'm a bow user so I was just spamming Snipe/Focused Aim on these things, but with my arrow travel time, it was pretty much too late by my second Snipe/Focused Aim and the tank was dead.
My question is why are these harder dungeons in the random dungeon queue before level 50 if they depend on people being max CP level to do them apparently? Cause we did not have enough DPS to take down the wraiths before the boss one-shotted the tank, every single time. I feel bad for that guy's repair bill

(I'm 23 right now so nowhere close to getting CPs at all so, eh)
