I always have a tough time deciding how to compose my healing guides for raid bosses. Talking about holy paladin theory is fun, but at the end of the day, we're actually being thrown into real raid encounters. We're expected to know how to heal through the incoming damage and handle all of the boss' special abilities. Knowing the specific healing per second of Divine Light isn't going to help you keep your tank alive. At the same time, there's no point in turning the holy paladin column into an esoteric version of StratFu by giving you a play-by-play review of every boss encounter.
Instead of boring you with a list of boss abilities that your raid leader is going to repeat anyway, I am going to try breaking down only what's specifically important for a holy paladin to know. You'll want to know when it's safe to use Divine Plea, when Holy Radiance is going to be most effective, and what you're supposed to dispel. Who should you put Beacon of Light on? Are any of our "Hand of" spells worthwhile on this fight? In addition, please feel free to ask any additional questions that you'd like to see answers to or add any suggestions.
