Improved Ender dragon

I strongly feel the ender dragon is way too easy, make it hard, its the final boss, add new moves, make it have more health, make it feel dangerous and have a more menacing aura. its the only dragon in the game, make it feel like one, add a roar attack that it does while its in the middle bedrock thing healing, the roar attack deals damage while knocking players back, add a new move where it makes the endermen around the player target it
