Diadem PF Issue

Maybe I'm missing something, since I've only done Diadem once via the PF and I wasn't the leader, but there doesn't seem to be a way to replenish a PF group when people leave. This lead to a situation where we had a few people leave, and those who remained weren't doing enough to get credit for chests. I suppose you could get people to promise to stick it out for 90 minutes, but between unexpected disconnects and people just deciding to bail, it seems like the current design makes it likely that one person is going to, in effect, get locked out because someone else decides to leave.

As of now, it's designed to not allow replacements. My only guess is so that everyone is on the same timer rather than having someone come in who has a fresh timer and everyone else is about ready to leave.

PF doesn't allow for replacements. Typically what we do is have people agree to a full run up front when they join of and ask if they have to leave for anything within that allotted period. If they tell us upfront that they can only stay a bit (at least half the timer) then we bring them along. If they just up and quit in the middle of the duty (voluntarily speaking) then we usually block them from joining future pfs and wasting people's time.

But in regards to the question you can't refresh in PF at all to my understating in any duty.

Makes sense; It seems like PF is an imperfect tool for this. The obvious issue is that PF can't be refreshed in an instance, which is either by design or a technical limitation. For most PFs in an instance, that's not terrible, since the group has a definite objective, and it's easy to tell when that objective has been met. Diadem seems like it's going to be a lot more like FATEs, where people are going to want to drift in and out. But unlike FATEs, which happen in open world, allowing PF to be restarted, Diadem won't allow refresh, and the timer means that it's not a simple matter of leaving and starting a new PF. Maybe the community will adjust and it will be assumed that Diadem PF is a time commitment, but it seems like the current system is less than optimal.

Diadem can't be replenished at all. Neither DF nor PF. It's by design. And you get a 2h lockout of reentering upon entering anyway. So it is a time commitment either via DF or PF. People also cannot be vote dismissed from it.

But going fully premade doesn't allow replenishemnt in any duty as well.

Had a FC run once when one of the people had to run mid way. So no LB but we finished the dungeon anyway.
