What healing abilities either scale with stats other than Healing Power, or don't scale at all?

Having to mix in +Healing talismans in order to improve my sustainability is a drag. Sadly, most active, and even most passive healing skills scale primarily off of the Healing Power stat. Which of course, I can't get any of if I want to max out my Attack Power or Health (or some combination thereof).

I know of a few abilities that don't require any +Healing to be effective. Turn the Tables is the most well known, as it provides a flat, instant, 642 healing at any time. Another option for Blades users is Point of Harmony, which provides healing scaled based off of your max Health, for a total of 30% of max HP over 3 seconds.

Are there any other healing abilities that scale based on Health or Attack Power, or which provide high, un-scaled returns for players that are not otherwise built for healing? I'm particularly interested in passives that provide these benefits, but active abilities are, of course, of interest as well.

No guarantee for completeness, but here's what I've found so far:

Active Abilities

Expulsion (Elite) — Blood — Possession

Cast: Instant   Cooldown: 60s

Places an absorb barrier on you that absorbs 100% of incoming damage and dissipates after absorbing 143 damage. This barrier scales with Attack Rating and not with Healing Rating. When the barrier either expires or is spent, it will deal 132 magical damage to all enemies near you.

Point of Harmony — Blade — Sharpening the Senses

Cast: 3s   Cooldown: 80s   Channelled: Every 0.5 seconds for 3 seconds.

A channelled heal that heals you for 5% of your maximum health each hit.

Turn the Tables — Green — Survivalism

Cast: Instant   Cooldown: 35s

A self heal that heals for 642. This value is not affected by your healing power.

Passive Abilities

Immortal Spirit — Blade — Technique

Whenever you penetrate, you gain a heal over time effect, which heals you 10 every second for 5 seconds.

Regeneration — Blade — Technique

"Martial Discipline" also gives you a heal over time effect, which heals for 57 every second while it is active.

Notes

The above passives don't exactly have any "special" scaling (other than Penetration rating), but they are clearly meant for self-healing during combat and as fellow Blade user I can say that Immortal Spirit has been very helpful in keeping me alive when soloing. It's meant to be used in combination with a Penetration focused build and equipment (be sure to include Four Seasons with it's guaranteed penetrating hits).

Including one or two defensive/tanking abilities (especially Martial Discipline in combination with Regeneration) is also immensely helpful in increasing survivability and lets you live through an "add" that would otherwise mean a visit to the anima well.
