Let's all brace ourselves for no healer mention in any capacity for the upcoming LL

[Allegor]

Considering SCH even already has a spell that converts shield into raw healing, it's not like they can't make SCH [and likely Sage] a more shield oriented, if not strictly shield healer, I think they just don't want to in fear of people claiming it to be way too difficult to play proactively (even though that's how the job is set up to be played but let's hide under the casual scapegoats), not to mention potential balancing shenanigans that I myself are too casual to think.

Also, a small yet relevant thing to take into account is that Consolation is a lv 80 ability, so unless you're playing on the current raid tier [Eden, ex trials, Nier raids], you don't even have it, meanwhile AST has its entire shielding kit as early as 60

Same could be said of WHM with Temperance. I remember back when WHM had stoneskin 2 and Divine Seal as abilities below 40 I think it was which did similar things as an aoe shield (long cast) and healing buff.

Difference being that WHM doesn't need Temperance to feel like a pure healer, whereas SCH has a weird gap between 50 and 80 where shielding falls to the sideline in favor of fairy and aetherflow ogcds - they don't even really need to shield, and that's supposed to be the job's niche.
