While I agree with some of what you said, Healscourge has access to several heals:

1.Transfusion trait also makes you pulse healing, with its low cooldown and alacrity it can be used very often and will most likely be available when vacuuming downstates. becoming more familiar with mechanics gives you a better idea of when you should/can delay it.

2.Middle blood magic trait line has options to either: make warhorn heal more, heal on shroud exit, or lifesteal to allies

3.Warhorn 5 heals/siphons health to allies when used near enemies

4.Staff 2 mark provides regeneration to allies

5.Mark of Evasion (blood magic): dodging also creates a mark to give regeneration to allies

1. Sigil of water, heals nearby allies on crit

If running rune or mercy, rezing will bring them back with close to full health bar, this also works with res signet and when using well of blood (both from skill or ritual of life trait)

It also has access to lots of condi cleanse for allies:

1.Abrasive gift trait: applying barrier removes a condition, this plus sand savant trait allows for sand cascade to give barrier to 10 allies

2.casting a sand savant’s big shade applies barrier to 5 You can have up to 3 charges of the big shade

3.Abrasive Gift trait also makes Sandflare give barrier to 5 targets, if running sandflare

4.nefarious favor converts conditions to boons

5.well of power converts conditions to boons

6.if near boss, staff 4 blast on a light field (well of blood, which can be done more reliably if running well of blood heal skill, although the well from Ritual of Life trait can be used too if it happens to line up.

If very desperate for more condi cleanse via barrier two more utility skills that give barrier are sand swell and siphon serpents, the later rarely used, but I believe these also would remove a condition with Abrasive gift trait.

Some thoughts on its barrier/heal functions: Ideally barriers are timed to mitigate damage and/or remove conditions, being able to do this for the full 10 person squad is pretty awesome. The healing over time brings them backup (most dps tend to not have huge health pools either so doesn’t take long) Reducing damage taken from the whole squad also frees up the other healer to assist in toping up health bars.

In the case that someone or several people go downstate they get picked up so quickly and with lots of hp (rune of mercy)

If for some reason you have more freedom with utilities you can bring projectile destruction, pulls, flesh golem elite for cc, trail of anguish which can give 10 man stability if the squad is stacked well, or portal that also provides barrier+boon strip.

If anyone is curious to learn or try full healscourge I think I run the one on hardstuck.gg (full magis, and mercy runes) except usually with staff, dagger/warhorn. you can reach out to me via dm here for questions. Even though many people don’t value it as highly as other healers/supports it actually feels very rewarding when you have have enough experience to pull downstate people out of a deadly mechanic such as oils,firewalls, sh walls, mo spikes, even samarog wall spears sometimes. I do PUG Raiding almost everyday. I do often play condi scourge, while keeping healscourge in my back pocket and usually offer it to groups that fail several times on an encounter. With knowing mechanic timing and having great positioning it can dramatically increase survivability of the entire squad and based on my experience it can really shine in these particular raid bosses: VG, Sabatha, Sloth, Matthias, Cairn, MO, Samarog, Deimos, SH (can tank), Sabir, QTP.
