Been reading your blog for a few years now and Ive got bitten by the Healing Bug (IE, supporting my guilds raid as a Tank and a Healer). How exactly do I want to spec as a Holy Paladin, what should I Gem and Enchant for - should I just base what I do off your own armory profile? Additionally, as a brand new healer - should I go with a FoL or HL build?
I recommend going with a 51/20/0 build. It's almost identical to my build, only with Aura Mastery. AM is good, I just haven't gotten around to respeccing.
Gemming and Enchanting, it's easiest to go for Intellect, with Spellpower as a second choice. I like getting set bonuses, so I use SP/Int, Int, and Int/Mp5 gems, but many paladins just gem straight Intellect (with a couple of mult-colored gems to get your meta-gem bonus).
I suggest going with a Holy Light build. One of the things a new paladin needs to learn is not to be timid with Holy Light, but to be willing to use it a great deal, even if there is a lot of overhealing.
For Glyphs, I recommend Glyph of Holy Light, Seal of Wisdom, and Beacon of Light. I use Seal of Light to max performance on Valrithia Dreamwalker, but Seal of Wisdom is better for undergeared paladins.
I also like the BoL/SS tracker. It's really useful for tracking Beacon and Sacred Shield durations.
Other than that, paladin healing is just a lot of practice. Keep Beacon and Sacred Shield up on the tank, Judge as often as you can, use Holy Shock when you move, use Divine Plea early and often, and don't be afraid to bomb Holy Lights.
