My favorite job is White Mage. I love big, AoE heals and usually played healers with large party heals in other MMOs. I also really like Holy because the first healer I played in an MMO had a big, AoE holy-damage skill (although it was kind of like Shadow Flare, only with larger damage). Most importantly, I find it really fun and almost zen-like to heal people, but when things get bad, it's exhilarating to heal through those situations, even if annoying at the time. Plus I work well under stress and thinking on the fly.
