End Dimension Revamp

I feel a revamp of the end is needed. I think end biomes that bring exciting new blocks trees and foliage would be amazing. There is a full dimension in game which is pointless once the elytra is acquired. New trees like a black plank or grey plank could be added. New mobs: The endergroot - spawns in a new biome which teleports the player when attacked, the mob could drop a new food source and ender pearl fragments which could be crafted into ender pearls. Ender iron ore could be added similar to the nether gold ore. There is a full dimension that needs biomes, foliage and mobs!! comment your ideas below
