If anything they should double down on job specific revival skills just so they are so abundand and you won't feel the need to bring that one caster to your team composition in the first place. Summoner can summon the eidolon of rebirth, Paladin has defensive holy magicks and Monks usually can use their Chakra enlightenment to get things flowing again.

But yeah I agree, Ressurection and Physick needs to finally go and from the ashes, they should get phoenix resurrection already
