I believe there is an argument to be made for loot boxes not returning any value when you receive a duplicate item. If the item is something you can equip and it only matters if you have either one of them or none of them, then receiving a duplicate could be argued that you received something of zero worth. I know some loot box systems work around this by giving the player something else when it rolls a duplicate like a minimal amount of the currency. Regardless, rolling and opening loot boxes are usually designed to be addictive which is my main issue with them.
