I had kinda the same thing happen to me the other day, with Dracula. It wasn't good. In many ways, the PK system is probably the reason why a lot of people don't join the server and there is such a low population right now. And although it seems unfair, it's part of this server, MVPs are like hunting for a rare white elk, many people could be hunting for it and they'll do anything to get the kill. It sucks for the poor people like you and myslef, but that can be over come with working hard in game farming expensive drops and buying dontaions items, from those same 'rish' people that PK'd you.
I'm not saying you're wrong, I'm just saying, think about what you're saying, Stop PKing on a certain map in a PK server. This is a hard point of view for people to sympathize with since this is a PK server and you signed up knowing it was. I agree with alot of what you said, but when something is unfair, you have to cope with it, adapt to what is happening.
That's just my two sense.
