This game is in desperate need of persistent progression content for main jobs...

Uhh...

Literally all content in the game is tuned to be possible to complete at minimum item level.

Hence why there exists the option to partake in content, while sync'd to minimum item level.

That's still related to your maximum capability. The higher your maximum capability, the harder the content (or vice versa), the higher minimum item level required to clear the content.

Err... No.

Since, minimum item level sync also means that materia are not factored in, since it will only be utilized if you're wearing melded gear that is that minimum item level.

In addition, we see that Savage has different minimum item levels for its bosses (While your "Maximum capability" doesn't change, since you can get all the loot from all the bosses by being not minimum item level)

Finally, we have Ultimate, which is lower item level than E7S/E8S, but is the hardest content in the game. It also has specific item level sync which is lower than the maximum capability (475 vs maximum item level gear which is 500 with a 505 weapon)

Yeah, that's just the nature of vertical progression. I'm talking in general, not per content. When they make content, they factor in what you can do. Unless they made a mistake, they're not going to make content that you can't do, but also, they'll have a soft limit to what you can do based on the content (with some leeway for job adjustments). That's why you sometimes see nerfs to jobs when they try to balance jobs instead of just always buffing a weaker job.
