I'm probably not the only one to notice this, but since 1.8 or 1.9 when they introduced biome based mobs and mob farming (animals) there's been way less animals and they've been spawning much less evenly. I think it would be awesome if they spawned how they used to in the older versions, IE: Beta 1.4-5-6-7 etc, and just totally remove farming, they spawned more commonly and it wasn't so linear to get material, if there was light, grass/dirt they would spawn/despawn.
