The titans might have built the wall and kept it safe. But the hunters would have never needed it since we prowl the wastelands and stalk our prey, then take them out with ease. We don't need brute force. We have stealth and precision. Hunter is not love, for there is no love being the predator. But, being a hunter is life, for hunting does not come with our armour, or weapons. It comes with time and skill.
