This has been posted by another user in the guardian forum but as it has not been noticed I am reposting it here at request of a user in that thread.
The issue: [Virtue of justice] for core guardian was doubled in its duration of burning applied. This works fine until the trait [Permeating Wrath] is taken which forces it back to a pre-patch state with half the duration.
Note this only applies when permeating wrath is taken otherwise it is functioning correctly.
Edit: I do see the user posted this in the pvp forum but as it has almost dropped off the page ill leave this thread as well.
