NIN, MNK, SAM, and RPR all have a CD that helps reduce damage to their person.

NIN = Shade Shift
MNK = Riddle of Earth
SAM = Third Eye
RPR = Arcane Crest

And these are abilities that are 1) specific to their job 2) reduce damage.

DRG does not have an ability that reduce damage. I don't count Life Surge as mitigation cuz 1) it doesn't reduce damage taken like the other abilities 2) you use Life Surge for the crit proc, and the self heal is just a bonus. When raiding, one doesn't chose to LS just to get a baby heal off, when Second Wind could heal for more.

So... IF the devs ever gave DRG a personal mitigation like the others... they could name it........ Drakenguard
