Worlds generation

Hello mojang ,  world generations are so messed up i mean sometimes you get worlds without a specific biome i'm not talking about the rare bioms I mean in general  , sometimes half of the world is the same biome and that's so frustrating it's really hard to create a world rn you need to make some changes with the world generation and I've noticed another problem that is the " mansions " most of the time they spawn more than 10k blocks away it's really hard to reach one last thing , the gravel i think that there's way to much gravel than usual in bedrock idk if it's a problem or not. 

 

That's everything i have thank you for putting so much effort working on Minecraft 💖💖
