Even I remember Inimical being toggled pk while churchless. However, Inimical, CoP did dominate PK at the time. Anyone who could PK worth a damn was in CoP, and many church fell under us. Many toggled PK off, also. But the PK system changed, numerous down times, etc, and now, PK is a frivilous thought on the backhand of someone wiping their ass. Changes to PK without changing the PK system:
During reckonings, only recall rooms should be safe, all other safe should not.
During reckonings, people in social need to be booted into the game.
During reckonings, people should occasionally flee from fear of the purple mist more often, reguardless if they're sitting or standing.
Levels 1-2 of poa should not be pk, lvl 3-4 npk, and level 5 cpk. This gives lower level people a little safety while souling/leveling, while anyone who wants to gain good xp has to work for it at higher levels. Make them fight for it. This isn't a teddy bear mud.
Add more CPK to the game, but not much, maybe like 5 more rooms to each large area (200+ room areas). and 3 to 100+ room areas.
that's all, and have a nice day.
