Truly awful idea.
You want to gimp a RDM spell to benefit other jobs when the spell was intended to augment a job that was starved of said buffs since they were removed from the armour they were on to make way for BLU.
I do however somewhat agree with it being able to target others, though I'd sooner make it targetable but with the negative of only RDM's natural (skill + merits) enhancing skill counting when not self-cast, so while RDM gets ~30% TA others will get 10%, though I'd rather that also come with RDM being put back on the light-style armour it used to be on before BLU, or the addition of other spells that augment RDM's abilities, the way they were originally envisioned, for example finally adding Faith and Bravery as job-abilities (not spells) would be amazing.
Similar to RUN's Inquartata but for Evasion, I agree though maybe similar should be added as a trait to NIN instead, though this topic is about RDM.
Always hated this personally, I know it was to give WHM something unique (in being AoE), but they already have it, they get more gear, and even MDB tacked on, should have been AoE for both RDM and WHM in the first place, with maybe single-target being added with RUN.
Agreed entirely.
