If that satisfaction is rooted in the collective balance of the job, sure. Years ago, I would say RDM was something like 1/7 WAR, 3/7 BLM, and 4/7 WHM. I did such in hopes to bringing that ratio more to 1/3 for each. The ratios today have improved only because our White Mage side hasn't directly improved with the cap increases, but it's still not melee friendly, nor enough for people to want the total package over a specialist. Or as noted for some, confusing SCH with RDM.
I imagine you saw me talking on trying to improve our caster aspects through melee, only to see the try-hards stomp their feet over how such and such should just be spells so they can keep doing what they're doing. Problem is, they're willfully ignoring that inter-job balance, or as I've more simply called it, its concept. Funnier still when they go the extra mile of trying to claim I wanna be a WAR and that there'd be no point in leveling other jobs if RDM could do it all. Nevermind things like MP being finite, lack of WS/SC variety, general abilities, and still-present inventory concerns.
But yes, I'm not dense. An 850 HP Cure IV is rather sufficient in today's game, possible enmity concerns aside. We're also the job with native Fast Cast, making it so we can pump those out comparably to a well-geared and merited WHM without the recast itself being a major concern. For all the times I've been on WHM, I can probably count the number of times I've actually had to use Curagas on one hand. And as long as events bleed temp items, the need for AoE cures or MP returned from cures themselves is not a super significant advantage. So yes, I foresee RDMs being married to /WHM or /SCH for the foreseeable future unless Stun is needed for some reason. Even then, my LS tends to VW with 2-3 BLMs so including a RDM in the rotation with a possible DRK around isn't exactly needed.
