The Desciption says: "Revives a fallen ally. The fiery resurrection blasts nearby foes with an explosion and knocks them down and Disorients them. Your ally will revive with most of their Hit Points and Endurance. They will also be invulnerable for a brief time, as well as protected from XP Debt for 90 seconds." It auto targets dead teammates but doesn't trigger. I trying manually clicking dead allies and even enemies alike, and it doesn't trigger. It seems like it happened somewhat recently as I never had a problem with it before.
