I agree with this. I'm not sure if the following is proven out but I recommend being within 10 levels between each piece of your gear and the dungeon level (this is especially important for your weapon and left side gear). Any more than that and healing becomes extremely difficult (until level 50 where item levels are desynced from character levels). Risvertasashi's adice for healing is spot on. If you need to spam heals don't be afraid to. Also take advantage of Presence of Mind for healing, and use Lucid Dreaming generously. Take advantage of freecure procs and any other long cooldown ability. If you need a cure 2 immediately don't be afraid to burn a swiftcast even.
