I think Moor Men Bewitchers, Broken Ones, and Greater Broken Ones might be messed up. They'll go into wild shape pretty much immediately in every encounter, and then start casting from their spell list, but they must have spell failure when shaped, because they'll botch every single spell. They'll just keep on casting and casting and casting, even though their spells aren't firing, until they're killed, effectively making them bystanders in every fight. I don't think I've ever seen one get a proper spell off against my parties; it seems like wild shape is their number one priority.
Also, they're all apparently vulnerable to Animal Empathy, when wild shaped, I'm not sure if that's intentional.
