Inflation is caused in all pvp, not simply 76king. Say you kill a player who loses a whip and a fury, worth around 6m. You get really lucky, and he drops an ancient statuette, worth 5m. You cash it in, and get 5,000,000 coins. Wait?! Where did the coins come from? They were simply created, thus leading to inflation. Yes, he lost a whip and fury, but the simple trading of a whip and fury does not entail the creation of gp like pvp does. The irony... "well" instead of "good," my friend.
