Those players, that I identify belonging to this category, see death penalties as a necessary evil. Stat loss is anathema, and experience loss is barely tolerated but only as long as it remains at the barest minimal level possible. To the risk taker, death is a constant companion akin to a second skin. Whether dishing out death, or receiving it, death is a natural and common effect of playing the game and something to be 'embraced', not hidden or run away from. It makes you forsake interacting with other players.
Someone always loses a fight.
If they lose experience, that means they have to re-max. That's bad because it retards the game. It locks players into a constant state of having to play against the game in order to re-max so that they can go back and do PVP competitively. If players stand to gain or lose the most by getting into the fairest fights, maybe it would discourage fairness. With this kind of system, id have to be monster bashing constantly.
