The Spear and a few more

U know that spears are really overpowered as it's considered better than the mace since it's easier to craft the spear than the mace and is easier to hit a spear than a mace, so u know that a spear has more attack range and if we use knock back it will be pretty much impossible to fight the one with the spear so can u not let knockback enchantments on the spear? And with the spear, the sword is pretty much not used now so can u make a bedrock combat update since Java already has one but the cooldown only applies like the ender pearl after being used and in the hotbar there is a cooldown just make the new cooldowns like that. And next, is the breath of the Nautilus effect because the effect is too powerful that even no one will ever use the water breathing potions anymore so please delete it. And last, please make the fletching table a use not just villager tradings since there's new weapons why not different way to upgrade the new weapon?
