Make the ender dragon more realistic. A dragon would not flap harder to stay in place, it would perch and turn towards the player more realistically. And making the ender dragon black when the entire background is black is just stupid. Make that battle feel more like a fight instead of a annoying loop of the same path. Give it more life, give it more detail, give it more ways to hurt you. Also when ever you spawn a ender dragon in creative it just goes to 0, ~, 0. Have it follow you or fly around you like it does with the endportal. Have the dragons be like the ones in skyrim, but blocky.
