The End Update

Add 2 new biomes to the End, except instead of using wood/trees as part of that biome, add an End castle in one biome because why have a End City when you can have an End Castle? In the End Castle you have to fight another variant of Enderman, Skeleton, Shulker and Zombie and the more rounds you defeat those mobs, the more harder they get and more rewards ranging from 2 items to 6 and when you beat the End Castle you can't do another round there EVER again. Meanwhile the second biome should be like an Enderman haven where all the Enderman's live, BUT it picks blocks around the player and its 1.5x harder than the Enderman to defeat and an End Tower with shulkers and rewards on top with Enderman protecting the tower, making it another variant of the Enderman.
