Note: I have never played a stamden so I’m not sure how good these changes would be however I hope its at least a step in the right direction thematically.

Animal Companions
Eternal Guardian - Can no longer be killed (excluding PvP). Remains through death. Attacks do frost damage.
Wild Guardian - Same as it is.

Cutting Dive - Same as it is.
Screaming Cliff Racer - Renamed to Freezing Cliff Strider (or some other similar name. It is a Cliff Strider though). Now a frost ability, a frozen Cliff Strider dives from the air and rams into an enemy, shattering. This would be a direct damage ability with an AoE component making it a good trash aoe spammable instead of pulsar for frost wardens.
OR Freezing Hail, which would have it be a summoning of several ice crystals that shoot down and hit an area. This could function more like the other morph of pulsar, not requiring a target.

Sub Assault - The shalks are now thorny vines and do bleed damage.
Deep Fissure - The shalks are now frosty or are ice spikes and do frost damage.

Fetcher/Swarm I think is alright but growing swarm should do aoe minor vulnerability.

Blue Betty - This appears similar to Betty Netch. Might as well make it frosty.
Bull Netch - This one’s fine.

Both morphs of Falcon’s Swiftness are fine. They don’t fit thematically at all but they’re pretty cool and I see more complaints about the damaging abilities.

Green Balance

I would change Leeching Vines into a single target bleed DoT. I don’t ever see either morph used but if they are used for anything, the usefulness should be added to Living Trellis as the healer morph.

Lotus Flower just needs help in general. Maybe Green Lotus can be buffed so that it would be useful to a Ro/Jo warden healer (heal while HAing, great for CR and KA executes where you need to HA while people are mega dying). Lotus Blossum can be buffed to give DPS some added damage if the thematic changes aren’t enough.

Nature’s Grasp also needs help.
Bursting Vines needs re-buffed (it is completely useless right now).
Perhaps Nature’s Embrace can be used to pull allies (only works on people in your group) to you.

Winter’s Embrace

Sleet storm is fine.

Frost cloak is perfect.

Gripping Shards should cost stamina and become thorny vines with damage that scales off DPS stats, instead of chilled status this has an increased chance to do bleed damage. This would give stamdens a class AoE that doesn’t require an ice staff without removing the slow/immobilize for tanks. This is one of the more important proposed changes.
Winter’s revenge is fine.

Polar Wind should no longer heal an additional ally. It’s a problem in PvP and I also see warden healers slot it when they shouldn’t. Tanks generally should not be able to heal other people. Sorc tanks can but matriarch takes 2 slots which helps with the balance.
Blast is alright, though I liked when the stun was immediate more.

Crystal shield is fine.

Finally, frozen gate. Frozen device should be reworked to either pull any enemy within it and then expire or stay up for a duration and pull an enemy within it every second or so. Right now, it’s a pain to use. If there are two concepts that both are balanced, then one can be given to retreat so wardens can choose which style of pull they prefer. Retreat should keep the synergy that lets players teleport to you.
