Why Villagers Are The Most Important Mobs In Minecraft

Villager are the most wonderful creatures in the Minecraft universe. They can trade with the player and trading with them gives the player some advantages such as getting some resources easily, gaining huge amount of experience points and a little chance to get special items like treasure enchantments. Getting these advantages makes the player very strong. 

Most people colonize a large amount of villagers in a place to trade with all of the villager types in one place like I do. Colonizing villagers makes them easier to reach and creates a safe area for them.

Trading is usually done with emeralds and since finding a huge amount of emeralds is hard the player can sell some items to obtain emeralds so they can trade with them easily, and earn more emeralds and goods. Also villagers have specific jobs (armorer, butcher etc.) so they can sell and buy specific items.
