Which way do you prefer your docks turned? The way mine are turned now, the attackers are drawn to the single wall near the docks. When I have attacked others with the docks flipped (walkway on opposite side from city walls) my troops will walk away from the walls and around the boat to attack the boat. Upside to drawing them to my walls is that double mortars are deadly. Upside to sending troops around the boat is its a major slow distraction for brutes who take forever to destroy boat.
