Ideas for improvement of the Caves&Cliffs Update

Dear Minecraft Team,

I got some ideas to improve the Caves&Cliffs update.

Many People don't like, that the caves became that massive and diamonds also became easy to find. I whould suggest, that you could just make the caves a bit smaller or make the old caves a bit bigger and edit them a bit. I know that you put a lot of time into the caves but what i wrote was just a suggestion you don't need to notice.

Best wishes,

Player
