These events do not have to be organized by staff, as Omg dead showed, players can organize them just fine.
Gearing is already easy, I don't think it needs to be made any easier.
If pkers want more people to pk with, they should treat their fellow players better. I'm not directly blaming anyone, but the pking part of the community is often regarded as a bunch of flamers that are disrespectful towards just about anyone. Nobody will try to get good at pking if they get flamed while they're doing it, it's not worth it to lose your gear over and over and get flamed at at the same time. If pkers can organize and help newer pkers start pking, that'll probably be all we need.
