Ever since the End had its update adding the End islands, End cities, shulkers and elytras it was impressive and fun to explore more of the End dimension. But it only takes 20 minutes to realise that now, the End doesnt offer much of any thing really. Before the nether update the nether was just a barren wasteland. players would never bother going back to after they get their nether warts and blaze rods. But after the nether update it's more appealing to come back to every so often. And now that the Overworld is getting a massive overhaul on it's natural caves and mountain generations you begin to think if the End will be next?
For the End update it should be implemented similarly as the Nether update. A few new biomes to add life and meaning to the desolate End islands such as Purple trees blossoming with beutifull pink and purple leaves with purple grass and plants growing out of the End soils. With interesting fauna lurking about every island to give the end more life. Instead of the boring I sores of Chorus trees we can instead have beutifull pink/purple/ black trees, grass and plants and animals. Maybe even more variety in endermen like the piglins and zombified piglins and hoglins!
Maybe a new ore or already existing ore making its home in the end to make mining more relevant and even more dangerous.
More added ruined structures and maybe even end villages to show that these endermen are intelligent. Like the piglins and how they barter. Trading with endermen maybe?
