Hello ,
My personal thinking about what is the best for a server is :
*Frist of all should be the disscusion with players , with the server comunnity, Regarding the server futures
* another thing will be to add uninique things in server gameplay but not to make it to much customs
* Take Care about comunnity needs speacking with them(i know those days to much ppls play l2 just for pvp and they forget the most important thing of l2 thats the sad thing)
* Avoid high rate servers this is a total unbalance of game i notice that on my own experience you will never achive the perfect balance
Thats all what was in my mind right now .
And Pleasee excuse my english
Thake care
Ps : You will nerver achive to please all players
