What expansion made your server decline?

I was just wondering about which expansion wiped out your server. Alot of people played up until luclin then quit, but there was still a large amount of people playing on my server (Rallos, then Zek). From what I remember there was still a reasonably large amount of people playing around 05-06 on Zek, but whichever expansion came out around 07 really diminished the population there from what I can remember.
