i know drop rate can be changed from chinse server i have play
and monster spawn rate like memora having characteristic of olgoc which will become 6 when atttacked
and custom drops
its not only that, you must keep in focus the big picture. if you plan a fast server, what kind of rewards are you going to give in a event? because players can get everthing by themselves. and thats only an small part of the picture.
when my server is up, rates will be low and all the players agreed with that, and except a few exceptions and a few guests, it will be a server for players in argentina only .
