Why balance jobs to just high-end raids?

[Payotz]

Homogenization currently only helps high end players have an easier time with the job they want to play, not casual players.

And that in turn results in the job being easier to play.
If you're having doubts about the direction job design is going, take a look at SMN and MCH.
Those are the latest examples of "complete reworks" they've done recently.

You're going to be fine. You are the game's target audience. Yoshi-P will always deliver.
