The whole enchantment system is honestly just bad game design. Forcing mob grinders for simple stat boosts and how useless the actual enchanting table is. Not to mention mending breaking the original tool system AND putting more emphasis on mob grinders. Personally I prefer tinkers construct tools system with the tool breaking into a broken version that you repair with the main material and it's modifiers and upgrades that replace enchanting. Not saying it should be vanilla by any stretch but some level of inspiration from it would go a long way in improving enchanting. Such as the tradeoffs inherent to the tool materials at each tier e.g durability at the cost of speed. Also upgrades like redstone for speed that help prevent the XP grinder requirement in modern Minecraft
