This isn’t fair for 2 reasons
1) here you are overinflating how useful casters are on the support by conflating 2 vastly different casters in the same sentence. “They have raise and they also have ones that do huge amounts of damage”. That’s a pointless statement because the game in the modern form is explicitly designed to try and make you not want to run double caster. You either get raise or you get PCT, if you take both you lose a melee and nullify PCT’s higher damage advantage anyway. You yourself have even expressed very strong desire to want to avoid double caster comps so it’s a little unfair that you are now using them as an example of advantages that the casters have over the physical ranged. The only valid point here is that SMN while classed as a caster should not be as easy as it is while retaining raise
2) casters (particularly PCT, BLM and RDM) if they do oppose equi-damage between them and the phys ranged do so for the same reason you oppose equi-damage with between the melees and the physical ranged; that being having an extra job consideration (casting or melee ranged) doesn’t play into an offered advantage because everyone does the same damage. If you support equalising damage amongst the ranged jobs you should also support equalising damage amongst the ranged AND melee roles otherwise your “support for the plight of the physical ranged” just reads like a veiled attempt for an excuse to nerf pictomancer
