Rangers’ Healing Spring is amazing.
I leveled a ranger, and I unlocked Healing Spring for his first dungeon run. It is a medium-sized, 15-second water field with a 30-second cooldown. Water fields combo for healing and regeneration. The base healing is nice, but the ability to proc regeneration and area heals is what makes this great for a group that uses finishers to exploit fields.
Staff elementalists get two water fields. One has a medium duration but small area of effect. One has a huge area of effect but tiny duration, along with a long cooldown and the rare “must stand still to cast” induction. In either case, you need to be in water attunement, which involves either using both in succession or managing your attunement cooldowns. They can, however, be used at a range, while the Healing Spring happens at the ranger’s feet.
50% uptime on a healing field is great, and that first dungeon group had two rangers. Placement options are worse than an elementalist’s fields, but you can hit “6″ anytime without attunement issues. Staying in the field while I attack, I can stack enough regeneration to last until the cooldown ends.
You play a ranger for ranged DPS with condition stacking and a pet. I did not expect to get a great support ability as an unadvertised bonus.
