There is nothing Rathena/Eathena or Rms can do about that o.o...
It's up to the server owner to be creative. The problem is Ragnarok is a really old game and the people that play have already settled in the servers they play on. So if you are making a brand new server, make it unique.
Alot of the servers I have seen out there are not so creative. They just download a bunch of scripts or wtvr and opens a server. There is only a few unique servers out there.
Yeah you do sort of have a point, alot of people are making or trying to make servers. But there is nothing anyone can do about it :/
