Not going to laugh at this thread, but instead i will just be honest. This idea was tried on a server , and it made pk way less fun why? because they don't last any longer no more. Signets make a pk last way longer, abusive or not, it's always good to find ways for other players to come back to an original pk spot if the spawn town is too far. Any ways the Server admin decided to cancel the idea, because in fact it destroyed the pk.
Facs could probably still spam signets if they tried hard enough.
That is the point. its more an endurance test than anything. Long drawn out and gets boring. Is nothing to laugh at on it. Most people have lives. No time for 3 hr signet wars.
Better solution would be to make the cooldown longer not that seal bullshit, that's just a dumb idea. My pvp suggestion would be make world bosses worth something so that guilds have something to fight over instead of just random PvP every day.
