Why that happened isn't as simple as just saying, "Because it's RDM!" though. XI was far harsher on progression and it technically saw the same disinterest or dislike of pressure with the healing role and WHMs. RDMs certainly weren't being invited for melee or nukes when you could've picked from a glut of specialists LFG, so the last resort for those wanting to actually EXP the job fell into playing healer. SMN faced similar. From this point, I'd also say BLU avoided a similar fate because SE outright made it impractical for the job to staff swap via physical spells being tied to main hand skill with a dash of limiting the spells one could equip. And perhaps a convenient lack of Wild Carrot as a party-target heal on launch. SE could've given RDM its own flavor to teeter it back toward a legitimate hybrid, but since Tanaka's a butthurt bastard over his HNM babies getting soloed, welp, we get what we got with a side of perpetual community snark against those who hated that outcome. See: Anyone who stirred the pot in the OF threads.
Edit: That said, I feel XIV's interpretation of BLM somewhat hamstrings the overall WAR/WHM/BLM mesh of RDM. Technically, the XI-style RDM some enjoy does exist now via THM and cross-class skill selections, but the higher end DoM gear and diminished performance can be an issue with tight DPS checks and other Fuck You Mechanics. At the risk of invoking some collective groans, when/if the job does see the light of day here, it is more likely to be a melee enfeebler than a backline healer/support. More generally speaking, we're absent the Haste and Refresh that made the XI RDM "so good" at it.
