The quest is ridiculously hard. The final boss makes me want to punch something really -blam!- bad.

yet another mission way to hard to solo with way to many restricted respawns that could have easily used match making always something with nerfing or adding something that shouldnt be there I mean wtf. Cant wait until this company goes under. Atleast you made it to the boss cant get past the 3rd room who puts five *&^%$#@ enemies right next to a door with no room at all I mean do they want us to be pissed at them.

It's not optional like many exotic missions. You finish it or you can't progress in the season.

It appears you play the story mission for the week, then it asks you to see Crow, then Crow gives you the mission.
