So I was thinking about how there is a max for trading up items of rarity, but what if you get duplicates? That's fine and all for steam users cause they can sell them on the market, but not console.
So what if we have it so that you can "trade down" aswell. You can only do this on items that you can't trade up on rarity, and you will only get 3-4 random common items so people won't abuse the system. (Example- 1 max tier for 3-4 common)
