I've got my own DB to release at some point but here are some general tips for you my good man:
-Make the mall in a place unused by any other server, repack, or database..it not only gets repetitive when the malls are located in the same spot all the time but it's just a sign of true laziness
-Make custom instances, if this is going to be a funserver repack then make sure you have content within instances that no one else does here if you dont have the knowledge of scripting try getting help from Gastric, Illidan1, or Insanesk8123..I'd help but I'm always busy :P
-Add BALANCED armor sets for different tiers for different levels
-This implies that you will have a level cap above 70 (use a newer ascent rev found at "Steph's Corner" (lol)
-Dont make it meant for instant 70, leave the option open to have a custom leveling area or to not..simply leave users a portal to spawn if they want and hide the leveling area somewhere unused
-Make custom cities OTHER than GM cities, players are most important in a server regardless of what many may think, they make up the server and they populate it
-While making this put yourself in the players shoes, when they start out what will they first see? Will they see a sign perhaps giving them instructions and welcoming them to the server? Will they see a warp NPC or custom warp ports with easy to depict names? This portion is very important when making a server of convenience. In other words, minimize the maintenance for the admin in game, and leave time open for out of game customization or simple enjoyment
Hope this helps
