You know, I'm wondering about something. Thinking back about the fact that "eighteen people increases the chance for loot to drop," what if the contents of the coffer, all ninety of them or whatever, are determined when the NM is killed and loot is first-come, first-served? I haven't done much Voidwatch and I don't know if anyone has postulated this before, apologies if that's the case. But if it is, maybe try letting people who don't have the most coveted drops examine the chest first? It would be interesting to see if that changes anyone's luck.
