I’m thinking with the Scalebreaker patch, you’d be able to do a fun Warden health-based healer. It wouldn’t work well in PvE, but I think could work well in BGs.

The idea would be to pump up max health (through stats and also gear like Green Pact and Plague Doctor) and then use Polar Wind as a sort of Breath of Life on steroids. I’m pretty sure you could easily push 60k health in no-CP even without using many glyphs on increasing health. Now that Polar Wind will heal for 25% of max health to an ally, that would make your heal on Polar Wind an extremely strong heal (both on you and an ally). You could then supplement this with Lotus Blossom—which is agnostic to max resources, will proc Toughness on you and allies, and will proc Nature’s Gift and major mending fairly easily. You also could use an ability that puts minor lifesteal on people—whether that’s Leeching Vines or Force Siphon. And you could use a monster set that adds healing—such as Troll King. That would be your healing.

In order to support your team, you’d probably want to then focus on four things: crowd control, sustain, group buffs/debuffs, and survivability.

In terms of crowd control, gripping shards would be a reliable group immobilize that would also proc minor maim very often and actually do good damage since it scales off of health. You could slot Turn Undead as well, which would be a good CC ability and use stamina—which is probably helpful for sustain—or you could slot Elemental Blockade. Use Permafrost as an ultimate for more group CC, though it won’t do a ton of damage.

Sustain would be really key here. Pumping up max health means you won’t have much max Magicka, and you’ll need Magicka to keep healing. But you’d have a lot of mechanisms for sustain. You’d take Blue Betty. Slotting Blue Betty would trigger the Warden’s recovery passive. Nature’s gift would proc a ton from your healing. You’d go Argonian (which makes sense for the max health and healing buff anyways). You could stack heavy armor with restoration staff to get massive Magicka regen from heavy attacks. Heavy armor would also give you sustain from Constitution. And if you need more sustain, it’d just be a matter of using sustain and/or max resource glyphs.

In terms of group buffs/debuffs, you’d want to take Expansive Frost Cloak. Elemental Drain or Force Siphon would be good and obviously not tax your resources at all. Permafrost gives your team major protection. And you could go Bone Shield for the group shield synergy.

Survivability would obviously be high by virtue of pumping up health and being in heavy armor. But you could take Bone Shield for a massive health-based shield (could use Absorb Missile as well. You’d lose the group value, but gain some extra benefits for yourself). You’d have Frost Cloak. You’d be minor maiming the enemy team a ton. You could go Race Against Time, Channeled Acceleration, or Bird of Prey to get mobility. Shimmering Shield would be fantastic too. Blue Betty spamming gives a slight heal and a cleanse. And, of course, Polar Wind would self-heal you massively every time you use it on anyone else. You’d be very hard to kill.

I don’t think this is ridiculously strong or anything, but you’d have the potential to have a ton of healing output with high sustain, on a character that is super tanky.
