For my clan it's simple: Drops no loot then it's worth skipping. We will do it once and then immediately save Crota to all of our alts just so we don't have to do it again. And once we learned we could solo that part like a week ago, we stopped doing it legit altogether. It's not a fun fight since it's so messy, and it has no loot. Why do it? Bungie rushed the shit out of Crota raid imo. It's super short and so many ways to cheese it all. I don't mind that they rushed it since we were so starved for content, but all this shit better be fixed in time for hard mode.
