Return of the King (A spear rework)

Spears, while useful, are niche, and could be much better and viable as a weapon. First, they should buff the jab damage of all spears by 1, standardize the attack speed of all spears across tiers, to 0.85 seconds, and increase the time you can hold a charge on later tiers. In addition, the spear can now be enchanted with piercing, which has been reworked (for crossbows too), to act practically the same as breach, ignoring 15% of armor per level, max level 4, incompatible with sharpness and smite. In addition, lunge will trigger on the change attack, not the jab. Now, buffing the other aspect of the spear, cavalry. Horse armor can now be enchanted with armor enchantments, like protection. Protection enchantments on horse armor are twice as potent (eg, double DR given), and horse have a new equipment slot, horseshoes. Horseshoes can be eecnahnted with boot enchants, and increase the horses speed and jump height detecting on tier, from +8% with copper, to +24% with netherite. Finally, in an effort to save the lives of many horses, when a horse drops below 3 hearts (6 health) they will buck you off and run. This makes it so your horse doesn’t die super fast. In addition, you can now feed a horse while riding it to heal it. Thats it for the bulk of my changes i would make, the restore the king of weapons to its rightful role as a powerful and viable, but not overwhelmingly so, weapon. I hope you enjoyed my idea. Thanks for reading.
