Remember that realistic trajectory we like to talk about? Often times shots will hit the wall itself instead of your units, especially if you have a further height advantage combined with the wall (Cliff + Wall for example) it can be almost impossible for attackers to hit that high up.
Also, there will be certain additions to wall sections to improve it in various ways ranging from boiling oil to increased defenses against piercing attacks.
Thank you for clearing that up - also, I am sorry I forgot about the hoarding upgrades.
