Saronia hasn't gotten that much bigger since 1.19 - there's a bit of a population increase, but not to a point where there's server queues. In fact, the population is small enough where I can still recognize a handful of player's names often enough while going all over Eozorea.

At this point I think a lot of smaller population servers should be merged, as a previous poster pointed out - or as you call them "ghost servers". Heck, at this point, I'd like for my small playing group of 3 players to be able to move our characters to a more populated server.
