I have a suggestion for x500 sever. Maybe it would be nice to add a trader with
Adena = Silver coin
Adena = Gold coin
Adena = Emerald coin
Adena = Hidden card
Silver coin = Gold coin
Silver coin = Emerald coin
Silver coin = Hidden card
At the moment I talked to people and I see that a lot of players has too much Adena. And they don't really has nowhere to spend it. Emerald coins are really big problem too. People are leaving server because they do not have nowhere to farm it. All locations (one location) is always fulfilled. Hidden cards are the one of the big problems too. Yes you can get them for Emerald coins but its nowhere to farm. Also, raid bosses spawn timer is really too long for this kind of a server. Maybe it could be lower?
I think my suggestions would could help you the old players more active. Also it would be way much easier for new players to start. They could farm coins in other locations and it would let them to be more competitive with current players.
Looking forward to hearing from you!
Have a nice day
