I'm becoming convinced that the people working on Minecraft have lost their minds.
A 5-level XP cost to rename items?
30 levels to bestow one enchantment on a book, from the entire pool of enchantments? With the weighting still applied?
And then there's an XP cost to apply the enchantment in the book as well?
Guys, if you're going to make the new feature you're adding as mathematically far from practical as anything in recent memory, save yourselves the time and work on something else instead. The mod community can do this work for you.
