What seems to have happened is that Shield of Righteousness (ShoR) has been moved to the Melee table. Previously, it acted like a spell that had to be cast from melee range. As a true melee attack, it can now be parried and dodged. It also means that ShoR will trigger a Seal of Righteousness proc, a Seal of Vengeance proc, or a Seal of Command proc. This will also give us another attack that can proc Mongoose or Blade Ward if you happen to be a fan of those enchants.

The take-away here is that Expertise just became a much more attractive stat for Paladin tanks. In the past, Paladin tanks really didn't need to worry about Expertise much as few of our main attacks were subject dodge and parry. We enjoyed Expertise more for the pseudo avoidance it provided. Now with Shield of Righteousness being on the melee table, Expertise is our best threat stat below the soft-cap of 26 Expertise.
