[2021] it's crazy how expensive many skill books are

You never played on White-Tiger where you need to craft each scroll with the price of the respective book? Well, then play next cycle, when you need to craft each scroll at the price of the book and first need to craft the book as a server-wide megaproject to unlock it in the sense of ages with a price similar to a mini WT computer lab! (Like in Civilization)

Or in other words: I somehow don't agree :D
