Let's put it this way i play multiple dps jobs and my dungeon runs go far faster as dps other then Red Mage, it just feels painful to play.
I now resort to going as mach for my dungeon/Expert Roulettes because it is just so much faster to clear.

But for the most part from what i have heard is that RM is not great at all for Savage, idk because i am DNC for that
