Another gripe I have with gearing is the fact that the gears you obtained through savage and tome are "One of a kind". Why is there a need to restrict how many copies of that same items in your inventory, when it is already "Unique" and can only equip one of them at a time?! Just to help prevent accidently getting the same item twice?

By just lifting that one single thing off the item. It allows for quick swapping between different class in the same role without having to meld new materia every time, as long as you are willing to put in the time to obtain the item. It doesn't break the game or suddenly let you wear tome or raid ring at the same time. All it is a simple quality of life.
