Role quest in Endwalker worry me. Job quest make this an RPG

[Rongway]

How much more could you care less?

Personally I couldn't care less about your caring .. there, that's the way to say what I presume you meant.

Grammar correction tip: make sure real grammarians actually support your point before being a grammar snob.

Merriam-Webster: Is It 'Could' or 'Couldn't Care Less'?

We define could care less and couldn’t care less on the same page, with the single definition “used to indicate that one is not at all concerned about or interested in something.” We do not put these seemingly disparate idioms on the same page in order to save space, or so that we might cause you pain. We do it because one is simply a variant of the other, and they are used in a synonymous manner.

[...]
Correct Usage: Either

[...] if you are the kind of person who cries out against this abomination we must warn you that people who go through life expecting informal variant idioms in English to behave logically are setting themselves up for a lifetime of hurt.

On topic: I'm working on getting a melee job to 90 now and then I'll be ready to binge all five role quest lines from start to finish and I'm looking forward to it. I don't need twenty different job quest lines this expansion. That would be 80~100 quests, almost as many as there are in EW 6.0 MSQ alone.
