I think you might be in the wrong place, this is the Lightbringer realm forum, not Whisperwind.
To me the server seems populated enough, plenty of DS pug groups and such. Most seem to be able to do 2/8H, some of them can do 3/8H. As far as the economy goes I don't really spend a lot of time on the AH, but I'm sure you can make an alt and check that out for yourself. As far as the PvP goes, I see people in trade on a regular basis looking for partners for 2's and 3's. There are a couple of RBGs that run regularly, probably not as many as the larger population realms. I'm sure some other people will say it's dead or whatever, but from my experience, this is one of the nicer realms.
