I think this server is awesome but it needs something that people will say o shit im staying.
For example pking, it should be at the clanwars place not in the portals but on the side of the actual place you stay in the hut its safe when u wanna go out and fight go ahead.
Make PVP Armour super super super super super duper uber easy to get, but make spirit shield harder and pvp weapons harder to get at the same time.
Also better drops when you kill someone like claws depending on what they are wearing I'm sure its possible to code something like that will take time around a week or so =).
Make donor zone a bit better by adding shops that noone else has access to.
VPS I do not know much about VPS but i do know what it does, so please get a better one if your planning on this server to grow.
Ill add on as I get more ideas =)
Hope you take some of theese ideas in consideration and apply them in the server
