Dear TFP
I like your system of reading and learning.
We have about 10 people running an active server, and there are some things we liked about it.
Collecting and learning books, this was a great system.
Also, players who are mainly active in looting and players who learn to make by reading books can get equipment of equal rarity at almost the same time.
This is a very nice balance.
One area I was concerned about is that players who had read the book would also have no advantage when they eventually get grade 6 equipment.
After talking to the server participants, I felt that for those players who worked hard to collect the books, their efforts should be rewarded.
In fact, once someone gets grade 6 equipment, there is basically very little lost.
Despite not having read the book, they have a knack for repairing it.
For example, what about players who can't make that grade of equipment because they haven't read the book, but need additional materials to repair it?
I have a somewhat old car in real life, but I have no knowledge of repairing it. If this car breaks down, can I fix it? Even if I could, I would need a lot of time, tools, and extra parts.
Sorry about the not-so-great translation!
