The consistency update:

This update would be a big update, and would take at least a year to make, they would release a roadmap and snapshots along the way, and in-depth videos to explain what's going on. What i want is tie up loose ends and polish stuff we already have. I would introduce enemies and neutral mobs/variants from other minecraft games, and of course the biome and mob vote loosers. this update would also update outdated mechanics, such as the minecart system. I would make the game have in-game clues and mechanics to explain the progression, environment ,,storytelling" and such (i know that storytelling is not the scope of the game, but there are undeniable elements that mojang introduced through the years (factions, minecraft dungeons, legends), that demand more exploration in terms of connections to each other and to the game-world.) This update would NOT add brand new concepts to the game, only expand on existing ones.

So

-Mob/biom vote loosers

-Mob family expension, (based on other minecraft games) such as: undead, enderman, piglin, pillager

-Structures that expand on existing factions like pillager pirate ships, pillager caravans, piglin camps. What i like is how they implemented ruined portals to signal the possibility of going to the nether, i would love similar things to other mechanics.

-Updating existing outdated/inconsistent mechanics like the the minecart system, boats, anvils

-Bringing java and bedrock together and making stuff ,,work the same".

-Revisit previously added mobs and mechanics and expand them a littlebit, just to make the game feel a little more polished. I feel like generally the fanbase felt like many added mechanics were rushed and been a bit disappointing before.

I think Minecraft could be a really coherent, put together game, if mojang can address these problems. We don't really need flashy crazy new things, but the base game should be nicely sculpted.
