I'm not really sure why players would ever cite the P8S adjustment in job balance discussions. They nerfed the check because they likely anticipated higher week 1 clear numbers irrespective of job choice. If it was purely a balance discrepancy, they'd just hotfix in specific potency buffs for those jobs rather than giving everyone an equivalent boost. I'm not saying that there wasn't a discrepancy that needed to be addressed, but this really is not evidence for that argument.

Also, anyone who thinks that Heavensward or Stormblood had a better job balance than Endwalker was likely just a WAR one-trick. Heavensward and Stormblood job balance made raid compositions absolutely stagnant. Previously the devs weren't even trying to achieve balance, and you had jobs that were viewed as both worthless and low skill across an entire expansion with next to no communication or feedback offered in return. This is the first time you can look at the numbers and say that they're actually making some effort to achieve numerical parity within role groups. Now they just need to work on achieving numerical parity irrespective of subrole (melee/ranged/caster), but I have a feeling that we'll have to convince them that this is the sensible thing to do first.
