I love the card art for Zealotry. That gearset is one of my favorite gear sets in world of warcraft. This is a ret ability that gives your hero and your weapons Sentinel- allowing you to strike twice in the same combat if you can afford swinging twice. This ability is susceptible to destruction in many raids- but it's play cost makes it almost worth it- especially for core PVP and classic decks. If I had room- I would include this in an equipment ret pally build.
