Imagine a family with parents walking with younger Dino's. If you agro them or kill parents or herd gets a boost in health or damage. Plus if you killed adults get to tame young Dino,but it would be passive tame for hervavors, and carnivorous Dino's you have to knock out with club or fist. Keeps it challenge for all. Movies you see younger with adult and books etc. Why not on ark?
