A major problem with threads like these is that forum posters approach the problems with the job by assuming the devs are thinking about whether the job feels fun to play and what would make it feel fun, but the developers actually approach the problems with the job by... checking aggregated player data to see whether Key Performance Indicators like 'number of players playing the job at X level' are being met, and White Mage will never fail to meet those KPIs because it's the iconic Final Fantasy healer, so there is no problem with the job.

It has the red and white robes, it has the canes, it has the cuteness, it has the flashy white magic. It's distilled nostalgia. Of course everyone wants to play a White Mage. So it receives only the most basic changes: numbers tweaks and a couple flashy-but-superfluous new heals each expansion to inveigle people to buy the expac. Why would it get more? All the KPIs say that it's doing fine.
