Redistributor

This set is often called useless, but it's actually decent on stamina healers. Its problem is one that is shared with most tri-stat sets; that it suffers an identity crisis. Redistributor provides a bit more burst healing potential, which is a major pain point, as stamina wardens have to face their target with a narrow cone to burst heal, short of using an ulti or something like Earthgore. I'd love to see this set committed to stamina healing, and reworked a tad to improve healing range at the cost of some potency.

Current:
(2 items) Adds 1206 Maximum Health
(3 items) Adds 1096 Maximum Stamina
(4 items) Adds 1096 Maximum Magicka
(5 items) When you heal yourself while at full Health, you heal an ally within 15 meters of you for 2347 Health. This effect can occur once every 3 seconds.

New:
(2 items) Adds 1096 Maximum Stamina
(3 items) Adds 1096 Maximum Stamina
(4 items) Adds 129 Stamina Recovery
(5 items) When you heal yourself while at full Health, you heal an ally within 20 meters of you for 2000 Health. This effect can occur once every 3 seconds.

Powerful Assault

This set is basically SPC / OLO for stamina, except it falls somewhat short of the mark. The health bonus isn't great when you compare it to the stats provided to magicka healers on the aforementioned sets. I'd ditch it in favor of crit. The 5-piece provides a unique bonus, allowing it to stack with Major Courage, and it is also easily applied. The problem is significantly smaller than Courage and it only affects four targets. There has to be some trade-off to keep it unique, but it could stand to be better. I believe keeping the lower benefit is fair, but the radius and number of targets could be better.

Current:
(2 items) Adds 1206 Max Health
(3 items) Adds 1096 Max Stamina
(4 items) Adds 129 Weapon Damage
(5 items) When you cast an Assault ability, you increase the Weapon Damage and Spell Damage of up to 4 friendly targets within 10 meters by 164, for 15 seconds.

New:
(2 items) Adds 833 Weapon Critical
(3 items) Adds 1096 Max Stamina
(4 items) Adds 129 Weapon Damage
(5 items) When you cast an Assault ability, you increase the Weapon Damage and Spell Damage of up to 6 friendly targets within 15 meters by 164, for 15 seconds.

Hunt Leader

I've never really tested this set, but I always thought it looked interesting. I thought it would be better in PvP, but warden pets in PvP aren't always reliable. Where this set could shine could be providing utility via pets. Applying a debuff that benefits the entire group would open up a lot of possibilities for this set. This could help stamina warden healers have more options than Dawnbreaker with Grove or Barrier for healing. This change would also make the 5-piece bonus a gradual benefit, which I would prefer over the slow bursts it currently provides. This would also be the first Staminasteal source.

Current:
(2 items) Adds 1096 Max Stamina
(3 items) Adds 1096 Max Stamina
(4 items) Adds 129 Weapon Damage
(5 items) When your pet attacks an enemy you have also attacked recently, you heal for 2433 Health and restore 1216 Stamina. This effect can occur once every 5 seconds.

New:
(2 items) Adds 1096 Max Stamina
(3 items) Adds 1096 Max Stamina
(4 items) Adds 129 Weapon Damage
(5 items) Your pet's attacks apply Minor Lifesteal and Minor Staminasteal to the target for five seconds, causing attacks against the target to restore 600 health and 300 stamina per second to the attacker.

Living Trellis (Living Vines morph)

I never find "when the effect ends" heals to be particularly effective. I need heals now, not later. This would give yet another spell to stamina users.

Current:
• Grow vines to embrace you or the lowest Health ally in front of you for 10 seconds. The vines heal the target for X Health each time they take damage. This effect can occur once every 1 second.
When the vines expire, they heal the target for an additional Y Health.
• Heals when the effect ends.

New:
• Grow vines to embrace up to two allies in front of you for 10 seconds. The vines heal the targets for X Health each time they take damage. This effect can occur once every 1 second.
• Affects an additional ally. Costs and scales with stamina.

Soothing Spores (Fungal Growth morph)

This is a good ability. I just feel the morph could be a tad more unique.

Current:
• Seed a large area of mushrooms that heals you and all allies in your frontal cone for 822 Health.
• Heals for 15% more on allies that are within 8 meters of you.
• Converts into a Stamina ability. Allies near you are healed for more.

New:
• Seed a large area of mushrooms that heals you and all allies in your frontal cone for X Health.
• Applies a damage shield for 10% of the amount healed for three seconds.
• Converts into a Stamina ability. Allies healed gain a damage shield.
