I played that way at the start, but even from a team perspective you cant continue to be a "back line" healer and just spam heals. I play as a sorc (full heal spec) and regulary finish with 7 plus tokens. You need to heal when required, cc and dot players. Do a bit of everything. From my perspective, I have enjoyed switching to this place style greatly. You feel more effective when being able to heal and do a little burst when required. All the best.
