I know lots of you bought adena, so you have no right to complain about farmers PKing your loop parties.
You really think they'd allow you do farm your own adena after you've became their customer?
You dug your own grave and most people only learn when you rub it in their faces. When you finance the farmers, you give them power to control most aspects of the game and leveling PK toons is just another very easy thing to do.
Enjoy it.
Now go make yourself a PK toon and PK these low level elf wizards farming adena, it's much more fun than people realize.
