They clearly announced that the items in the chests would be of better quality and more valuable.
The only problem is the presence of a large number of pieces of furniture (placeable items in large quantities are harmful to the performance of the servers).
As far as I’m concerned, I prefer to loot valuable objects rather than stones and other resources that are easily obtained.
In addition, the presence of objects obtainable only with the knowledge learned makes this knowledge useless (why learn a recipe if the objects for it are numerous in the chests?).
