I feel like both NIN and DRG need considerably better personal survival cooldowns after seeing the ridiculous RPR one (Though the latter moreso due to it also being a DPS cooldown).

The ones on SAM and MNK already mitigate considerably more damage over the course of a fight, so the only real value NIN's has is that the mitigation is high enough to be more likely to save you in a panic situation where you can tell your HP isn't high enough to survive a mechanic...but that's something that shouldn't be happening in the first place.
