I happen to talk to players and most of them dont go pvp. They kinda play the game for pvm, getting rich and quit then go back again bcos of the nostalgia. This sounds selfish to suggest but this server mostly have custom features right? so why not experiment look for ways to attrack people to go pvp? From the games I went the pvp have some sort of reward to character like stats and the resources are only drop on particular pvp map thats why ppl go there hunt. This is where interesting stuff start.
If this thing didnt work you can remove it since its just an experiment. I am looking at ppl on pvp room all they do is randomly target ppl sitting there and chat. There are no purpose ryt?
