To get to the point quickly, a good number of servers have gotten mass transfers over the past few months, particularly due to the nature of Alexander Savage breaking statics and causing people to leave for a "better raiding scene" (usually Greg or Balmung).

This isn't something you can fix by designing future content to be more appealing for players, since they aren't there anymore in that server. Speaking on my perspective, my PF never has more than 10 listings at any time, and it's nigh impossible to find, let alone start your own static due to the absence of a raiding scene.

That being said, I think a database-wide PF should be taken into consideration. It allows players to draw from a larger pool when it comes to party/static formation. While it seems a lot to implement, I honestly feel that this is something that needs to be pushed for, lest we have dead servers leading to players dropping the game entirely if they don't want to transfer due to circumstances.
