I've suggested it before
jump event and relunch on Steam would save this server. Instant 50 level will attract many players to CoR and keep them here. Also NGD need to make monthly patches with new content so people will stay for sure.
Haven is dead. No new players at all, terrible grinding, empty map, chat and no action at all. Time to make steps such as instant 50 level to bring Haven back to life and anniversary is perfect for that. I don't see any other way to fix Haven, really. NGD do it for us, please.
