I totally understand why the system of one piece at the end doesn't work for level cap. But is there any way to make the final boss drop two chests? Or guarantee that those chest have a piece for at least the jobs playing?

I know the devs are obsessed with RNG. That's obvious. But it gets really frustrating and not fun. Ive run the new dungeon every day since it came out. Im on 32 runs and have yet to see the healer top drop. It might be a little bit of me acting like a baby but its so frustrating to just keep doing it with no guarantee idk. Maybe its just me
