Someone else (Braven) just posted a bug/exploit in another thread that I expect will be resolved soon. They stated that if you equip a druid with medium armor and a shield, cast shield of faith on them, then wildshape them and cast mage armor on them, and then release the wildshape... the mage armor effect will stay... bumping their AC up to about 24.
