More Biome Variations and Generation

Minecraft has several different biomes and improved generation. I feel like there are still parts that are not ready to be left that should be changed. Rocky plains: This biome would look like a plains biome but with different rock variations covered in moss. Streams would occur in between some of the rocks. It would not have as many trees as the normal plains biome, making it a bad place to start your world. This biome would only occur when a plains biome generates next to a lake or ocean. Things like that could be good variations of biomes which would make the game a little more interesting. The warm to cold biome blending is fine, but I don’t think that should be the only way biomes generate. In addition to the current biome blending, mountains should spawn in ranges. Mangroves and swamps should spawn at the edge of jungles, savanna’s and other warm biomes near water and not in the middle of an island or with no water.
