I\'ve got an ideas on pk\'ing. Here they are:
An idea I stole off Runescape and twisted a bit. Perhaps there could be a \'lawless\' land that \'even the Gods avoid\' that could be for pking. These lawless lands I\'m talking about is like an abandoned village, a wild forest, ets. There would be no special advantages or disadvantages in these areas, other than you can pk. And since people can use the terrain to their advantage, there should be exciting guild wars to fight in.
