I'm not sure if its intentional, a bug, or simply an oversight, but the Law and Order pvp talent doesnt seem to interact with Blade of Wrath or Divine Hammers.
Law and Order should work with Blade of Wrath in the next build you guys get. In most situations Honor Talents should work with replacement spells, but in this case we didn't feel that Law and Order should cause Divine Hammer to apply Hand of Hindrance.
