Transferring stuff among people holding items is a pain. That's mostly due to fr's lack of any sort of hoard filter or attach a full set of things with 10 clicks (ie if you had checkboxes of 16 items click yes, all attach) vs 48 or whatever is needed for a full pm.

Funds movement is easier but also you never know who will need to take a break from game/have internet issues right before a push.

Also having to keep personal vault separate from flight vault via tracking spreadsheets, just give me extra vaults fr I will pay to unlock them.

It's better for raffle security if one person doesn't hold everything but the work involved in constant movement is a struggle.
