Holy Paladin
Rotation
Opener: Blessings of Kings and Wisdom out, Judge Light or Wisdom on the boss, then Flash of Light the tank.
Priority: Flash of Light as the filler, Holy Light for big tank damage, Holy Shock for instant emergencies. Downrank Holy Light to stretch mana. Keep Judgement of Light up on the boss.
Cooldowns: Divine Favor + Holy Light for a guaranteed big crit; Lay on Hands when a tank is about to die; Divine Shield only to bubble-bomb a mechanic.
Forever notes: Forever's Paladin rebuild (Oct 30) moved Illumination and the Holy Shock talents; follow the starter build on the builds page, not a Classic guide.
Stats
Healing power, then Intellect (bigger pool and more Illumination crits), then Spell Crit, then mp5 and Spirit.
Crit is a mana stat for Holy because Illumination refunds the heal. Do not sleep on it.
Numbers for every spec and a gear comparer: stat weights.
