Revamping The Main End Island [Future "End Update"]

The End has a center island that is very open, but very lacking and somewhat boring for the dragon fight.  Here are my thoughts:

• There could be areas players could hide to avoid Ender Charges, such as large spikes of obsidian around the end, and/or maybe some obsidian piles as barriers, or as something to get in the player's way.
• Replicate some parts of Minecraft: Story Mode into the island design.  There could also be some small, floating islands dotted around the outskirts of the Main Island, and maybe some End Crystals can be on some of them.
• Have the Obsidian Pillars be jagged, but still straight.  This could make traversing up pillars much more interesting and it may look pretty cool to have.  Maybe there could be crying obsidian on small parts of the pillars.
