In recent times, I have come up with an idea that might be put into minecraft, provided that someone tells the minecraft team about it. So anyways, I had a great idea to add ACTUAL human mobs into the game. They'd look like the default skin, just not manually used. So, in the last update, trading with villagers has been introduced, and so has zombies and skeletons picking up armor and all items. Why not have a human that can trade, and pick up items like armor and potatoes? They'd also be like iron golems in past versions. They could attack you if you attack them. They'd randomly spawn around the world, but, they could also spawn in their own HUTS. Since witches have huts, I thought it would be cool to have the mob have a hut too. So in short, the humans are just other people.
The next mob I'd like to put in the game is the Pigmen race. We've seen them as zombies, why not normal? This mob would be the same as any other pigmen, except alive, and is normal. They would be almost the exact same as the Human mob, but they won't trade. This mob would also randomly spawn in the Nether. Their features are the same as the Human, and the undead. (Zombies, skeletons, etc.) They WILL swarm you if you attack one. They DO have golden swords. They spawn mostly in the Nether Village, which I am about to talk about.
So, the Nether villages. They are exactly the same as NPC villages, except they are made out of nether brick, nether fences, and nether stairs. The crops would be nether wart and the water, obviously lava. These are the things I'd like to see in future updates, like 1.5. If you can contact anyone in the minecraft crew, PUUULLEEEEAAASS tell them about this! It would mean a lot, and get you some cool new mobs and features!
