No, they where dumb and the drops where screwed up. The whole PvP worlds update was jagex responding to the loss of players when they removed free trade and Pking imo.
No. It takes out the aspect of original RS. I can see how many newfags thought in their head that that was the definition of pking. It makes me laugh.
I vote yes, but only for a few worlds. Pking at the grand exchange and camelot was epic. I want it back.
