Let's clear something about the dead coffers you would get at the end of the progress.

First: Those were not dead to begin with,anyone could get them and I doubt that at the end of the run none wanted that piece for a second job.

Second: when the item dropped, you couldn't get a second piece of that gear and was because of the unique mechanic of the items, you have one? Can't drop another.

Third: the rng was on the items, not on the rolls that players would apply making it all less painful to see when lose all 3 items because your roll suck, and to be fair... This isn't extreme, you can't simply rejoin and get something.

Forth: I have all the accessories for my main job but I can drop everything over and over and keep the coffers in my inventory so one day maybe I will change class, while for week people that want to gear up don't have a single 470 item.

Fifth: Is it really fair for 1 person to drop everything, just because got luck? Clearing in pf is already hard by itself, adding this to the roulette each time you finish a run, ain't fun i tell you.

If you are not complaining it's probably because
A you dropped stuff
B you are in a static
C you don't care at all

And about statics, my irl job doesn't allow me to have a precise time line for static requirements so I can't join one even if I could.
