Just decided to get the Purifying Light morph to use on my alt bar for my healer and I really wish I could get that skill point back. The pool is so pathetically small, it's basically useless. Allies fighting bosses aren't even close enough to be in it when it appears. On small mobs, you move out of it with the slightest movement. Among many other Templar abilities or morphs that need some love, I think this morph needs looked at. I'd rather see it have a much larger radius but lowered healing, or even just have it send out a single wave of healing in a larger radius and be done. That said, Backlash itself isn't that bad of an ability, in my experience.
