Well silver,
i think the wrong with your server is the Client,
I bet that if the Client was Interlude,Based on L2J,with features,you server will have more than 250-300 ppls.
now if you dont wont to make it interlude,i dont know how its impossible to attractive ppls,i dont have see your server (in.game)but as you say thinks are missing,so if you have java knoweldge,you can make your own codes,you can use your imagination for it!
but i bet thats the prob is client!
