Pathed (Wild update)

The Wild update is all about immersion, so my idea is animal paths.  Animal paths are paths frequently used by a herd of animals throughout the years, such as a path to a watering hole.  Mojang could add pathed blocks to the generation. such as a trail leading down to a river.  Mojang could make it so cows and other animals will head to the closest water source block or a pre-established watering spot (via world generation) that has actually randomized path gen ( but not requiring water just a behavior).
