The most important stuff is in the center. The mortar is backed up by the wizard tower, the air defense is well centered, and the clan castle is well centered as well. Additionally the storages are separated in different compartments and each one is covered by two defenses plus the mortar. The town hall is outside of the walls but it is covered by some defenses, so that if the attacker came for trophies it won't be too easy to get them, but if he does it then I have 12 hours of free shield
