Healing is now a state of permanent hatred.

[Brandedblade]

In ShB, he gained
- Strong regen on soil, making it both mitigating and restoring health
- Forced crit on whatever you like, especially excog/indom
- Seraph with 2 charges of aoe shield and the fairy casting stronger version of embrace with shields
- Fey blessing, basically aoe heal

And you say that that what made it powerful is its healing output without loosing damage..?
It's mostly the same from this point. Scholar became a more oGCD powerhouse.

As scholar, you'd always have to weave those abilites in someway, the tradeoff being a slight loose due to clipping with broil or weaving with miasma II or currently Ruin II.
If anything, scholar from a healing perspective became more powerful with minimal lose. You can now even run all around the arena and still do damage to a correct degree (200 is way better than 100 or 80 like in HW/SB)

Gutting the "extreme micromanagement" was not necessary for that.

Sacred Soil requires trading an Energy Drain to use, and while Recitation mitigates this cost for Excog and Indom, it's a 90 second cooldown that effectively only affects either every 3 indoms or every 2 excogs.

Seraph has double the cooldown of Rouse did back in stormblood, and even then all those powerful Seraph heals still cost weave slots to use, irregardless of being able to offset the potencies with Energy Drain.

Even with the buffed ogcd healing recieved in Shadowbringers. There is still the trade off of weaving space and thus potency loss. In stormblood not only was this mitigated by having more access to Aetherflow via Quickened Aetherflow, and thus more Energy Drains over a fight then we get now. But the fact you did not need to create a weave slot for any fairy action, combined with the target able stronger embraces and access to Rouse to further increase Embraces potency. A stormblood sch could do far more lossless healing just by virtue of having abilities that could be used and spammed without clipping or creating weave slots.

This assumes you're using Indom and Excog on cooldown. Which is rather rare (especially for Indom) outside ultimate, since there are better tools available.

Seraph has double the cooldown of Rouse did back in stormblood, and even then all those powerful Seraph heals still cost weave slots to use, irregardless of being able to offset the potencies with Energy Drain.

The use cases of Rouse and Seraph differ. Seraph is mainly used for its Consolation ability because its Seraph Veil heal, while more powerful than Embrace, cannot be targetted. Its more of a mitigation cooldown than Rouse's single-target burst (with proper planning).

The only healing ability in SB's SCH that was truly lossless was Eos' Whispering Dawn. Everything else costed a weaving slot and/or Aetherflow.
In ShB, everything costs weave slots (and there are less of them available) but there are more Aetherflow-free healing abilities: Fey Blessing, Recitation and Seraph.

Comparing the two, the only net loss would be on Whispering Dawn, which now costs at worst 80 potency to weave. Everything else seems strictly better resource-wise.
