Like I said, I still imagine NCM and GEO as offshoots of THM and CNJ, respectively. It won't happen but a man can dream. I'll go with Repossession for now (... though maybe I should drop it to "Repossess"... but "Resurrection"... damn my obsessive need to make things match).
I might consider moving that list I've been writing to the OP, since it's fairly buried now.
There's something to be said about 'homogeny' however. Under the current system, a rez is a rez is a rez, you don't really care who cast it or how you got it, just that you can get on your feet; because of this, we can have skill combinations like Thin Air/Light Speed + Swiftcast Rez to save the healer tons of MP (hence why I'm not concerned with the necromancer being able to reduce MP costs or cast times specifically on their rez, on a cooldown) or let RDM machine-gun multiple instant rezzes in a row. It's the rare utility with no use or benefit for the casters themselves, so with each being essentially the same, it can't really be gamed more than any other heal.
But in a system where, say, you save MP and cast time on your un-life insurance by switching to Necro VS Astro returning you with more health and MP VS Scholar giving you an extended immunity phase VS White Mage Raises having a lower Weakness timer?
Then the entire resurrection game changes -- nobody cares whether you saved MP 'cuz that doesn't affect them and ideally you won't be using it often enough to justify not having Swiftcast, but DPS will beg for WHMs to rez them so their performance is better faster, Tanks for SCH so they can get last longer, Casters and other Healers for AST so they get back in the game sooner.
Suddenly people have preferences for who rezzes them, which leads to performance dips as people stop to check what they're in for or decline casts or ask why soandso couldn't rez them instead, which leads to raid stacking to ensure the best results, which leads to community outcry, which leads to balance discussions from the devs to make sure raid performance is unaffected and job distribution is adequate. Bear in mind that RDM is already getting its damage tuned around the utility it brings by chaining Verraises, it costs a quarter of their MP with only LD to bring it back, and this is all assuming it keeps the most basic version.
It's a slippery slope.
(Also oof @ me double-posting twice in a row, I'm honestly lucky to have seen you replied at all with you editing more in.)
