So I've done quite a bit of searching here, the official forums and on Google at large. I have yet to find anything even close to resembling a "Basics of Healing as a Holy Paladin" that is remotely up to date with the current patches. I'm not looking for information on what addons to use (I prefer to learn my class/role first, then move to add-ons that I feel will add to my enjoyment and effectiveness), but rather a simple overview of how to get started.
A bit of info about my current knowledge: My main is a Level 80 Combat Rogue with some ICC experience. I also have a Level 65 Frost Mage. I know how to kill things up close really well, and from afar fairly well. My Paladin, on the other hand, is Level 46 - and I have been levelling him up through questing and the Dungeon Finder as a Tank. Recently I dual-specced him and want to try my hand at Healing for a change of pace in the dungeons, but I can't seem to find any basic information on healing to help me get started.
