A couple weeks back, I covered the changes to protection for the 4.0.1 pre-Cataclysm patch that usually goes out a month(ish) or so before release. The point of those patches is so that everyone can play with the new class features and get everything figured out before the chaos that is the actual expansion release. Now it's time to do the same sort of coverage for ret pallies. If you haven't been following the changes thus far, it's going to look odd. There are new class concepts and skill/buff consolidations.
First off, picking your spec now has a lot more meaning from the get-go. You receive most of the passive buffs that you'd have to spend 40 talent points getting in the past for free at level 10 that are responsible for making your chosen spec usable. As an example, you get Sheath of Light, Two-Handed Weapon Specialization and Judgements of the Bold. That provides your attack power-to-spellpower conversion, your weapon damage bonus and your mana regeneration. All of this just for picking the spec. In addition, you get a new attack called Templar's Verdict that we'll get into later.
First off, let's talk about the biggest change to our class in the expansion: holy power.
