In case you did not know, as Retribution Paladin you might consider clicking off the Chaos Bane Buff to increase your dps.
„Your melee attacks have a chance to drain a Soul Fragment granting you 30 Strength. When you have acquired 10 Soul Fragments you will unleash Chaos Bane, dealing 1900 to 2100 Shadow damage split between all enemies within 15 yards and granting you 270 Strength for 10 sec.“
