The healer, the White Mage, is a pure job, in action as well as name. Survival as a lone White Mage; it's hard. I spent the first chunk of my gameplay on my own, no parties or groups or Free Companies, so I suffered, and died, a lot. A LOT. -.-' And I was told by many I should just cross-job, even a little, just to get the knowledge. But in my eyes, and based on my original intentions for my game career, I only wanted to be the one to patch people up and keep them going, because someone has to. I don't mean to get dramatic about this, like it's real life, but even in video games, the healer is the "bones" of the community (military speak). Without them and their specialization, it's not possible.
