Due to the variations in the items and how many possibilities there are this seems like it would be sorta unreasonable. Plus imagine the amounts of threads that would be made saying, “ devs why you no increase “x” drop rate to “y” drop rate because (selfish reason here) “. It’s also the same reason why STS would try to evade releasing drop rates on chests and stuff. Releasing drop rates often discourages players from buying, farming, or playing due to them seeing that, “the chances of this are so low so why even try?”.
