Instead of Platinum Ore Packs, Damascene Ore Packs, can the bosses drop the ores? It wouldn't change anything. The items are bound (or so it says, never really checked) but they can be turned into warrior seals which can be turned into ores again to trade. All this would do is save time.
The special chests (from the 7th, 8th and 9th trials, where someone has to dig the chest for rewards) can also give the items directly. Since the chests don't drop anything and there's really no point in putting the items into chests.
