Paladin

Holy Paladin

Healer

Light's Vigil finally gives Holy an AoE answer; single-target healing and buffs are still the class's calling card.

Protection Paladin

Tank

Seal of Fury finally gives Protection a taunt; Consecration AoE threat makes it the dungeon tank to beat.

Retribution Paladin

Melee DPS

Two-hander, Holy Strike and Seal of Command; twist your Seals in PvE and keep Holy Shock in your back pocket for PvP.
