Lightsworn: Leveling as a Holy Paladin in Legion
https://twitter.com/WarcraftDevs/status/663884048868085760 It's official: Blizzard wants healers to be able to quest in their healing specs in Legion.
Lightsworn: Playing the Shockadin
The Shockadin is a Holy Paladin build that trades some of our healing power for the ability to do some legitimate DPS. Named after our signature healing spell, Shockadins use Holy Shock, Denounce and Word of Glory to sear their foes with righteous indignation. It is not a true DPS spec, and we should never regard it as one. But it is absolutely a viable alternative for Holy Paladins who just want to quest without having to hit things with a big stick.
