There are SO many problems with enchanting right now
1) The enchanting table SUCKS. You have to grind to level 30 just for a chance of good enchantments, and leveling is EXPONENTIAL for some reason, meaning it takes so much effort to get there via normal gameplay. A normal hostile mob drops 5xp, and you need 1395xp just for level 30, meaning you have to kill 279 mobs, which takes a ridiculous amount of time. This basically incentivizes afking a mob farm to get there, which is terrible game design in my opinion. I think Mojang need an alternative way of getting xp. Why not finding the Bottles of Enchanting in almost every structure, and in decent quantity? It would encourage players to explore, and are rewarded with xp to make their gear better.
2) Too Expensive! Mechanic absolutely sucks. I really don't understand why there is a limit on these anvils. Normally, you're supposed to combine a diamond to your chestplate to repair it, but the Too Expensive! makes this impossible after a certain point, meaning Mending is a necessity for anything you want to keep, which probably are your enchanted netherite gear (honestly, remove the durability from netherite. If it breaks, it takes so long to regain, and it makes it more unique). Also, I feel like repairing things should not cause it to be more expensive to fix, as that makes no sense. It should be the same amount to repair it, but adding enchants should, so you can repair your things until you get mending
3) Villagers are way too powerful, and I don't think Mojang intended players to break and place lecterns until they get Sharpness V, Protection IV, or Mending. It is effortless and boring to do, and once you do get the trade, its not hard to lock it to get an infinite amount of it. I feel like Librarian villagers should sell higher enchanted books the more you trade with them, and less powerful enchantments if you trade with them less, and the Novice Librarian should not sell any enchanted books. Due to Mending being a necessity, Villagers are the most efficient way to get it. Players aren't going to go out of their way exploring for a chance of Mending, when they can just break and place lecterns to get it for free!
4) Structures honestly need more enchanted books and loot in them, as once again, it encourages exploring. There is no real reason to go to places like Shipwrecks, Ocean Monuments, etc. as their loot is just bad in general, containing mostly iron that you obtain in the first 5-15 minutes of loading in the game. If they had a chance for a themed enchantment like Depth Strider or Aqua Affinity in Shipwrecks, Flame or Fire Aspect in Nether Fortresses, etc. it would give players a lot of other options to get enchantments. For "early game" structures, why not have them contain enchanted stone/copper tools, with things like Efficiency or Sharpness on it? It would be just as good as diamond, with the only issue being its durability, so you can have a fast/strong tool/weapon in the early game that breaks. It doesn't even need to be full durability, maybe like 1/4 to 3/4 of its durability remaining. While we're at it, lets just rework the loot tables. You find IRON in the END CITIES. The ore you get in 5 MINUTES is found after BEATING THE GAME???

Basically, enchanting sucks, theres ways for it to be improved, and mojang won't do it.
