Hi this is my guide for 3.1.0 PvE Healing.
-=WARNING=- Before any flame, read this: I made this guide 90% from my own knowledge/experience, the 10% comes from WoWHead/Thottbot.
This guide contains the following sections:
1.0 Spec
1.1 Stats
1.2 Gear
1.3 Abilities
1.4 Glyphs
1.5 Addons
1.0 Spec
Theres few pretty nice builds out right now, Im gonna link the most used, I highly recommend it. The World of Warcraft Armory
1.1 Stats
In 3.1.0 Blizzard nerfed the regen from mp5 and spirit by 40% which sucks, you can go oom now.
Not much to say about...
Mostly you want to stack crit rating, mp/5, haste rating, intellect and spellpower.[NOTE] Intellect is by far the best stat, because it gives mana/spellpower/mp5/crit, very nice!
1.2 Gear
After you've hitted 80, prob. retri specced, go to AH and grab some blues/epox if you got money (: Rep. rewards are good also, I Recommend farming Argent Crusade rep to exalted, for 2xEpix!
After you got your holy gear, maybe 1400+ spell power and 16k mana unbuffed, start farming HC's, theres pretty nice site where you can see all the HC/Quest drops Kaliban's Class Loot Lists: Paladin
1.3 Abilities
Flash of Light, I recommend using this when your low on mana, everyone says holy pala healing is "FoLx1000" No, sorry.
Holy Light, This will be now your mainspell, spam it. You can have alot mana reduction, from Glyph of Seal of Wisdom, T7 Set Bonus, and from Libram.
Beacon of Light, This is our little AoE heal, only 2 targets tho. This spell is huge manaeater, use it only when whole group is taking dmg.
Holy Shock, Use this when you need to do some burst healing, Holy Shock+FoL rules.
Sacred Shield, When you cast this the player receives buff, and when the player takes dmg, shield will proc, absorbing 500+75% of your SP. Useful on tanks+DPS.
Divine Favor/Plea/Illumination Use those, when you want +healing,mana,or mana. Not much to say.
Those are your mainspells what you will be using.
1.4 Glyphs
I highly recommend these glyphs, Im using them myself
Minor Glyphs
-Glyph of Blessing of Wisdom, Increase the duration of Blessing of Wisdom by 20 min, when casted on yourself.
-Glyph of the Wise, Reduces the mana cost of Seal of Wisdom spell by 50%
-Glyph of Blessing of Kings, Reduces the mana cost of Blessing of Kings, and Greater Blessing of Kings by 50% [Optional] Glyph of Lay on Hands
Major Glyphs
-Glyph of Holy Shock, Reduces the cooldown of Holy Shock by 1 sec. [Optional] Glyph of Flash of Light
-Glyph of Seal of Wisdom, While Seal of Wisdom is active, the cost of your healing spells is reduced by 5%
-Glyph of Holy Light, Your Holy Light grants 10% of its heal amount to up to 5 friendly targets within 8 yards of the initial target.
1.5 Addons
Grid This one I like, best raid layout there.
PallyPower This one keeps everyone blessed, easy.
There's alot more those two are the one what I prefer.
Good luck PvE'ing ^^
