What even is the purpose of all those non melee/blm jobs?

[Azuri]

Alright, you got all of those posts out of your chest.
It is really basic. If a Monk, a Red Mage and a Dancer all did their rotations to a target dummy for 10 minutes, you would have a good grasp of their uninterrupted damage output.
But the game is not about spanking target dummies. Sephirot does his Pillars mechanic, you get yeeted around the map, what does the output look like disrupted?
Dancer is least disrupted aka most consistent, melee/casters are less so. Sure, the nuance comes in how much individual players are able to minimize that downtime, but that is good! Having nuance in your gameplay is good! But it is also good to have straightforward, consistent jobs for people who like that too! There is such thing as a "healthy amount of imbalance".
This is how you are supposed to look at it, not how "difficult" things are.
And I am not naive, I know people want to frame it in meritocratic light with "winners and losers", but god that is so cynical, PF can be so cynical. It is not enough to play a job for the sake of mastery, that must come with some inherent prestige and status.

ARR fight design called. They want your weird fantasies where melee have even 5% of forced downtime back. Because what you are talking about has nothing to do with Endwalker.
