Right... So of the casters, only Red Mage should have Raise, because... That's harder to balance and you have no idea how that would be properly balanced? Sorry, but it sounds to me like you've either just given reasoning for Red Mage (and Summoner) losing Raise utility entirely, or (as I suggested) making Raise utility a non-unique thing... If it's not unique and effectively a role skill, then it is far simpler to balance, because it's essentially a non-factor when balancing the casters. Making a Job weaker because, as you put it, it can salvage a run from a scenario you don't even want to be in to begin with, is just a really poor design choice.
Something as potentially powerful as Raise should either be on none of the casters, or all of them. That way their individual balancing is not determined by having it or not. All get it, or none get it, either way you make having Raise a non-factor when balancing them, which really should be the goal.
Honestly, yeah. But with how the games been going lately, I favour Job identity over pure utility, since SE apparently doesn't. I favour gimmicks over every Job having a carbon copy of the same toolkit at this point.
