We both know that white mages are not used in dungeons and farm content for the most part. The only reason you even see a white mage is because double scholar in raids does not work well with Adlo shields not stacking. Astrologian will allow two strong healers who are updated healers to the shifting focus of adapting in 3.0 and beyond while the static and much needed updating on tool kit white mage is still a healer made for 1.0 days. If scholar shields could stack you would see white mages benched already.
When a job is only useful because of two other jobs gimping each other you know there is an issue. White mages need more then just raw healing and a gimmick holy that is weaker then just job changing to scholar and doing faster dungeon runs. You can delude yourself and pretend white mages are fine even if you main one but inside you know you go scholar for really getting crap done and just go back to white mage to stand around in Mor Dhona.
