New update suggestion: Kingdoms and Castles

A new structure could be added: the castle. It is a worn down stone brick structure with a main tower and a wall closely around it, it should be pretty tall but with lots of cobwebs and gaps in the walls. The spawning of the structure could be that each one is different with certain rooms scrambled around with different levels of decay. The Loot would not be super powerful but could consist of some diamond and maybe a new armor trim also in a knights barracks there could be iron or chainmail armor on stands. It is a rare overworld structure with a small moat around it and a drawbridge either up or down depending on rng. To fit in the lore the castles were final lines of defense for the ancient race of builders against the illagers and you can find some in the dungeon of each castle. Now the kingdoms part of the update allows you to enchant a banner so that if it is in your inventory players with that same banner color enchanted can’t hurt you allowing alliances and battles in this new castle biomes. PvP could also get the addition of lances so you can be a knight atop your mighty stead. In summary: this new update gives people new structures to rebuild loot and even customize and make there own gives and give pvp some teams and a new weapon maybe even using the fletching table to make tnt arose to siege a castle. A benefit to the devs would be the lack of a need for a new mob and the reuse of random spawn mechanics. Thank you for your time and hope you consider.
