Most high tier ships, especially the BBs use the all-or-nothing armor scheme.

As the name suggests, armor up the important parts, disregard everthing else.

Important lessons were made that made ship designers turn to the all-or-nothing scheme. The Battle of Denmark Strait was a perfect example. HMS Hood could only survive a few hits from the superior 15-inch shells that were fired from the Bismarck (Hood's 14-inch barbette shells did little to stop those mentioned shells), thus, leading to Hood's fate. The Prince of Wales had the all-or-nothing scheme (Hood had banded armor). She was able to take several 15-inch shell hits and after withdrawing, was still fine and was not in any danger of sinking.

The same concept can be seen here in WoW (I have seen some WoW videos). As Alias knows, the bow and aft sections do some disapointing damage. AP at the citadels do serious damage, if they penetrate. Other sections may be unexpectidly thin, leading to over penetration, and thus, leaving the section otherwise unharmed, compared to the shell penetrating and getting stuck in the ship.
