Modified Mob Spawning in Cold Biomes

     Cold biomes now have Frozebite alongside the Stray, so Mojang should eliminate the normal Zombie and Skeleton variants in cold biomes. This will make the cold variants more dominant in their respective biomes, but since they are more powerful, Mojang should make them slightly more rare. This creates balance between hostile mobs and their biomes, and contributes to the immersiveness of Minecraft.
