Have you ever wondered what would happen if in one of the updates a bug would appear, a bug that would lower the rate with which you get UVs while crafting weapon. Or even lower the rate of getting UVs other than low?
Some people would report it as bug, other people would come up claiming nothing changed they got amazing UV just minute ago, other ones would say things like "random uvs are random","you cant predict random stuff" etc.
Players wont have enough means to confirm it as bug, devs might dont take players complains seriously thinking its regular rant for not getting shiny UVs.
IMO it would be terrible.
Soooo are you trying to do something? o_O
