i doubt WHM is less impressive than a SCh. i ran trials and dungeons at 70 on the SCH and FEY union is so unintuitive. it's basically a weaker CURE 1 on a 10 yard range with a 3 second cast time. 3 second cast time because of the wind up animation before your target gets it's first tick of heal. when your fey union target runs out of range the fairy just STANDS there
