Huh, it took you 3 years to realize that? Some of us were on macro 24/7 long ago, right after the game died.
Not to mention that you didn't need parties for many years now. Only the total lamers were making/joining parties, the better players were just solo/duo everything. It just got more pronounced last 1 year or so.
Just accept that the live L2 is on its last legs, barely holding. Enjoy until it lasts.
