Large Village

These villages would be different from normal villages. They would have much smarter villager, a school where kid villagers learn their profession (warrior included) from villager teachers, each villager would have their own personality. Mobs would attack normally and the villagers would fight back, the kids become adults after their profession is chosen, there are also miner villagers, along with a mayor and council. There is only one of these villagers per world. (ps, I know Mojang doesn't want villagers to fight, so maybe only villagers from this village would fight, they are smarter there.)
