Adaptive mobs

Hey!, As we know minecraft mobs are kinda well how do I say it dumb and I know most would disagree but it would be more fun if we could have an option to make the mobs adapt to how a player plays, like if a player is a pro keeps on killing the mobs and escaping the mobs adapt to the way that the user plays for example if a user kills spiders when they aproach straight to the player the spiders then start climbing upon to near by objects to attack from above just to make the game a little more fun and harder and this could be an option in the settings menu to turn it on or off so not everyone has to deal with it
