If you really want to make a successful server, you have to work a lot on platform and also some parts of the gameplay, not just make enchant rates, an armor set and you're done.
For example, when me and Leeroy tried to make a server, I worked like 15hours straight in order to fix every SINGLE skill, and I mean it.
Then worked on every custom NPC, tested them over 10 times, tested each class in order to get some balance and then start making rates and such.
