I read in the comments of someone's YouTube video that if someone on your fireteam offers their "broken blade" to the thrall statue before you that you cannot offer yours. Now, you would think the simple solution is to just run solo. Well, yes, you can but the next statue is after the first encounter and the third is after that. Once again, if it is in fact just these three you need to offer to and you don't even have to finish the Deep Dive (presumably) then that's not so bad since you can run it without matchmaking. But doesn't that, yet again, defeat the purpose of playing this game with your friends? If I run it with buddies, only one of us can make an offering each time. Meaning, we get to the third statue and then leave and start over again so that everyone can offer to each statue. And even that is, once again, assuming you do not need to finish the Deep Dive to progress the quest. The reason we don't know this is because you didn't give us a quest tracker to know how this actually works. So, is the inability to offer at the statue per person a bug? Is that intended? Do we have to finish the Deep Dive to progress? How about some answers?
