Take, for example, patch 4.4 (and really a lot of patches, but let's focus on the final tier of Omega just for simplicity's sake). White mages could clear it, but no one took a white mage by choice - only if they couldn't find the other healers - because SCH and AST were just better. More healing, more DPS, more utility, more mobility.
Patch 3.4 was the same. "But white mages were great for dungeons!". etc
So I say yet again: If the standard is only "can clear the fight", no job adjustments have ever been needed. For healers, tanks, and DPS. SE might as well have just left everything the same at the beginning of each expac.
