Well it doesn't affect Pkers in that sense, there isn't any balance to Eco/Pk servers unless you have the playerbase to cover it. It has to be easily accessible to items for Pk servers if lower player count or more common drops. The only way a Eco/PK server works is with a big player base like what BS has back in 2009-10 for it to work.
Just a theory, don't take it too serious I hope haha.
