There have been server merges since you left and more on the way. I haven't been anywhere as a lower lvl lately though; the population seems fairly stable and it's pretty easy to solo on most jobs now days so finding a party isn't that needed anymore. Granted, your probably starting over from scratch? If so it might be tough still, with extra boosts to xp lately though, the lower lvl's should be quick to get through.
