My case is really specific. But lvl 50 WHM and SCH in 8-man content (preferably min ilvl synced)
We gained so many oGCD over the expansions that basics precasting spell aren't a thing anymore. And because mana is not an issue anymore, you can DPS and ignore that part.
As for Scholar, since you don't have that powerful Indom and such, succor pre-mitigation and sacred soil usage are a lot more impactful.

I don't really know how to express the feeling of playing healers at lower level, but it somehow feels like you miss a lot of things in your toolkit but somehow, it feels refreshing to have to rely on your own knowledge of the battle and actually use more GCD spells to fullfil your jobs properly.
