I think this whole line of thinking is wrong. People are incredible hunters, those that specialize in hunting. Crafty, dangerous, innovative. We have plenty of modern examples of people hunting dangerous animals with very basic tools. An average lion pride can't kill an elephant. A specialized lion pride can. Humans are like this, but way more. Way, way more. My default assumption is "these people knew how to hunt hippos." A neighboring band may not have.
