I recently soloed the Duality dungeon, but because of time restraints(I'm a single father), and getting stuck at times; I did not fully complete this triumph(Solo Thoughtstealer). Although I beat each checkpoint, and went throughout the whole run(no skips, no help)after defeating Caital I got no triumph(only one I'm missing for the title Discerptor as well). I personally think its wrong of Bungie to punish people who can't sit and non stop play each encounter to earn this. What do you think?
