No longer causes Bastion of Glory to apply to [Flash of Light]. For Holy paladins, it now increases the healing of Flash of Light on others by 35% per stack (up from 20%). For Retribution and Protection paladins, the effect on Flash of Light remains unchanged.
Patch 5.4.0(2013-09-10): In addition to its current effects, now also causes Judgment to generate a charge of Holy Power for Holy Paladins. Stacks of Selfless Healer now reduce the cast time, mana cost, and improve the effectiveness of Divine Light, Flash of Light, and Holy Radiance.
Patch 5.0.4(2012-08-28): Redesigned and now available to all specializations as a talent. Your successful Judgments reduce the cast time and mana cost of your next Flash of Light by 35% per stack and improves its effectiveness by 35% per stack when used to heal others. Stacks up to 3 times.
Patch 4.2.0(2011-06-28): Can no longer be dispelled and cannot be stolen via [Spellsteal]; and, in addition to its current effects, it lowers the cooldown of [Word of Glory] by 5/10 seconds.
