it has a LOT to do with people failing at boxes. The more you fail, the more likely you missed your chance at getting the item. I got the fishing rope you were looking for 4 times in one day (was doing book burn for other character). Too dismiss someone not getting their boxes open is ludicrous. If you are only opening 1 in 100 boxes do you really think your chances of getting the item is the same as opening 99 out of 100?
