Going to answer this in two ways. The first way will be for the character Rakka'li, and the second will be for just straight up game mechanics.
Before that though let's consider how many people are stuck in this Log Horizon type situation with me. Assuming there's about 6k players per server, and assuming that perhaps 50% of the player population is on when the change happens, and given what we know about class distribution there's going to be anywhere from 350-500 more White Mages running around than there was before. Also we have to consider how unbalanced Miqo'te male populations are going to become, while it's likely that the adventurer population is going to be a drop in the bucket compared to the total offscreen Eorzean population, there is going to be a sudden influx of Male Miqo'te - particularly of the Sunseeker variety. We could spend a whole topic devoted to how that would shake things up.
If I'm in Rakka'li, the character's, shoes then I'm not exactly powerful or influential. In fact I won't be doing so hot because of the situation he's left me in. I'm borderline destitute and not exactly well liked, though I am lucky in that I've got moderate Healer talent so that I can at least be valuable to the Stillglade Fane. No echo and little combat skill beyond some self defense training means that I'm probably not fit for anything heroic. Overall not a terrible place to be in since there's security in obscurity. With a more level personality at the helm rather than Rakka'li's less than stable personality controlling things, I could build a fairly safe, decent living.
If I'm Rakka'li, the level 50 White Mage, then things are way different. On one hand I've got access to forbidden - and potentially dangerous - powers via White Magic, and my forays into Coil and battles against the Primals have left me with numerous powerful artifacts and a reputation for taking down the big baddies. However just because I have this stuff doesn't mean I know how to use it, I've  pretty much been put in the seat of a high performance racing automobile even though I barely understand manual transmission. I'm going to have lots of enemies and perhaps expectations to take on responsibilities that I'm just not able to handle. It could be a very dangerous situation that's only made bearable by the fact that there will be many other adventurers in the same situation, so there will be some safety in our numbers and our ability to organize.
I think my best shot in that case would be to work with the Stillglade Fane and use my clout as a Whitemage to align with Gridania. Needless to say I wouldn't be doing any dungeon delving for a long while.
