Baby steps.
I don't think we need to concentrate on any of these though. None of these get the attention of new players.
Now 'n days the majority of servers get famous because they have zero flaws. Your going to want a pro coder to log on, and enjoy the server, and want to help code it. Because not only are 317's so easy to play with, you can do WHATEVER you want with them.
So thinking of that, changing the Mining spot to Falador, is absolutely 110% a waste of time and effort. CW, absolute waste of time because not a single person will enter that portal if you think about it. And the partyhats, Osiarus got it. They are indeed called a rare item for a specific reason. These don't get obtained as easily as the full armadyl, or spirit shield sets do. The Economy needs a fixing as it is, so why throw sets of Phats out there when theres 5 people on at a time?
Got to think more outside the box. Think about things that would catch your eye on Runelocus.
People look for Unique, Different, and Enjoyable servers.
Whether that mean tons of Staking at the duel arena, or Dicing @ Home, or Skilling for money, or PvMing for Armadyl not doing slayer for 20 minutes. Etc.
There is much much more to worry about rather then those small things.
Maybe add advanced gnome course. Etc.
Add some different minigames. Nomad? no one wants to go kill nomad for fun. Or Angry Goblins???
There is SO much you can do with a 317 server, this source out of all sources, too.
So simple to just google stuff you want on your server, you don't even need to know how to code fully.
