A large part of the fun in PKing is that people do not want to be killed and having a stream of people to kill. A lot of that 'stream' comes from people who are roleplaying, and that is why the world map is free-for-all and that is why there are insides to go in. Having a server dedicated to this would be as useful as the "PK Center" level was. This is what I mean by 'activities are not so evenly divided' because pretty much everything depends on each other. Events do not, but there is not a constant stream of them to warrant its own server and there never will be.
There won't be a poll placed on the Facebook page because it is not the staff's decision to implement something like this. We couldn't do it, and adding a poll out of nowhere wouldn't change anything if the owners of the game just don't want to do it. I have a feeling that they won't.
