No, in fact, I heal more as a White Mage. I'd argue more Healers have quit to become Sages as I do not consider them real healers anyways. Every time we get a Sage in our Party I pray we have a Red Mage or Paladin because they are much better healers then Sages and at least Red Mages has revive and make up for the Sage being a horrible DPS class that they should of just made a DPS like a Bard.
