I wonder if you put some sort of forced deposit, upon attacking, that lasts say a week or so. Like a huge sum of gold. If you start a fight, then for a week X amount of gold will be lost if you die.
Of course there might be edge case get arounds, but basically the main thing of someone coming up and shooting you has more of a cost than "I logged in, hit create character and ran at the first person I saw". You'd need to earn all that cash, and your the one vulnerable in terms of cash.
But that'd require a cash sum that's available to your next character if your prior one dies. Though that's not exactly a crazy setting breaking thing - we have banks and wills in real life. We don't have spirit runs from the nearest graveyard (that I'm aware of, anyway)
