It's reasonable for a casual player to farm a book and clear the book challenges every 2 days. No reason you couldn't have a weapons done within the first month. I am on my 3rd book now as well, and I only play for a few hours after work, and some weekend grinding. Fortunately the new beastman dailies take very little time to deal with. Hope to be up to like book 6 by next week when coil gets echo #1. The chest armor & improved weapons should make things a lot more manageable.
