People getting bored...Look at some of the people here on KO4life, this week there playing a warrior, next week a mage, then there quiting...then there coming back as a rogue.
Items and lvls making a difference in pk thats USKO.
In a way you proved my point. If I have to "work" for my items I would just play USKO. Cause at the end of the day, when I'm ready to quit I can sell out. I will get more value for my "work", in my opinion.
