Because in DSR on my RDM I required more personal mits because I didn't have something like Manaward but I provided Magick Barrier. Selfish mitigation has value, just different kind of value and it's often less valuable than party mitigation.
Anyways, Black Mage got a buff. RDM/SMN didn't because they have raise and that tax is definitely about 10% extra DPS for the BLM or so.
Also, as far as I see. Raise doesn't provide as much utility for the whole infinite raise from RDM plays against them. Their big burst is their mobility and brings them into melee and we all know they ain't having priority over Samurais in raid for mechanics. Summoners only think about casting when it comes to Ifrit, the worst of the three elemental primals for how little it gives for the caveats it provides. Still the better overall pick because you don't think, you can call mechanics and lead the team as a Caster DPS.
Red Mage has Magick Barrier, great. Let us remember a group cleared TOP with 0 healer :) a group of individuals that are an anomaly but nevertheless proved a point.
Black Mages are just getting buffs to deal same DPS than Melees.
Just... all ranged and casters minus BLMs got ignored, as expected from Endwalker and they made buffing even more easier.
My hot take; Monk is very simple. Like Samurai. Like Summoner. Other jobs will eventually become like Summoner.
