[Autumn]

Insulation isn't considered basically at all right now as an addition to Verglas' kit, the buff it grants only lasts 3 rounds and the people you would want to use it against tend to also have Winter's Bite themselves, you can justify it's usage in the Evoker or Ranger matchup generally but I see not a lot of use for it otherwise.

I'd like to suggest that it gain an HP Regen effect to accompany the ice resistance, scaling about the same as other HP Regens do, this would make it a lot more useful as a support button to throw on an ally or yourself. Naturally it would gain a cooldown of like 4-5+ rounds if it becomes an HP Regen.

I am also biased to suggest this as I've wanted for a way to get something similar to cryotherapy for Verglas for a while now, I was thinking it'd scale 15/30/45 HP Regen, with the 3 round duration this makes it a 135 HP Heal, 180 if you were to spirit it instead, this seems kinda low for a heal over time imo but matches up with Verglas' ability to use meditate to extend the effect and sustain longer, as well as the possible other boons it can grant.

More importantly (to me) it'd help me fill a thematic niche I've wanted to fill for a while now without changing my subclass, a completely selfish request on that end.
