And not everyone know how to do smart combining or takes time to do the research, they just want to play the game.

TL;DR: concerned about running into anvil level limits because of the new villager book nerfs, later tested and found I can still get my max tools without running into limits so I don't have any problems with the anvil anymore

What with the new villager nerfs, I’m not looking forward to trying to smart combine the nerfed books from librarians while still getting the rest of the enchantments on my tools. Instead of working with Efficiency V, Fortune III, and Unbreaking III from the start we now have to use multiple Efficiency III, Fortune II, and Unbreaking II books to recreate those books. Not sure if it’s even possible to get a max tool through combining books from villagers anymore, but I’m leaning towards “no.” I could always just luck out on the enchanting table, and if I recall correctly a random one of these books can be found through exploring, fishing, and raid rewards, but I’m not feeling having to go back to RNG for my enchantments. I liked the reliable, repeatable source of an enchantment. I wouldn’t mind the nerf quite as much if the level cap on the anvil got removed or at least raised.

Also, these lower-level books are an unlocked purchase as a reward for leveling a desert, taiga, and jungle librarian respectively to Master. At least Mending and Silk Touch are still themselves (although you have to level a swamp and snow librarian to Master respectively for them).

EDIT: Just checked with this calculator and you can still get max tools, including max picks with Fortune III, even with the villager nerfs. Still upset about the villager nerfs but less upset. Calculator will not let me check if I can still get my favorite sword enchant set with these new limitations though because the calculator won't take over 11 items. (Unbreaking III = x2 Unbreaking II, Sharpness V = x4 Sharpness III, Mending, Fire Aspect II, Knockback II, Looting III, Sweeping Edge III, sword: that's 12 items) I checked myself in-game and found I could still get this sword. My worries are assuaged and so I have no grievances with the anvil.

IMO the level cap makes sense if Mojang wants to keep players grinding for more materials to replace their gear. But, Minecraft just isn't that kind of game to begin with. Plus, by the time it starts having that effect, grinding for materials just isn't that big of a deal anymore.

Besides, replacing your broken gear doesn't make for good gameplay anyway. It just distracts from building the big project you need the gear for.
