I'm loving the grind/hardcore feel of this server but here a couple of suggestions to make the experience more fun (imo).
1. More resource drops
Stuff like uncooked noted lobbies and sharks, noted rune ess etc.
Maybe from higher levelled monsters (Hellhounds, Heroes, etc.)
So you can merge skilling and pvm more.
2. Clue scrolls/Mystery Boxes
I really like the surprise and gamble of both of these things.
Adds something more to do when you're tired of pvm and skilling.
3. Points system
Points give you encouragement to do something, I think the best one for this server would be either; Pvm points (1 point for each monster killed) and/or Skill points (1 point for each skill raised)
This would give players a goal to reach if you added a point shop (it could sell things such as rune picks/axes, rescources, rares)
4. Events
Getting the staff to hold events for players really helps grow the community, I've seen some good events on other servers like, Minigame parties, boss raids and drop parties, pking events always seem to get a bit salty, however.
