Exactly, I was recently playing the Darksouls and I found it more exciting to see how the players interacted, obstructing the story, it would be great, as it says, I could be wandering some time in the region trying to hinder players, or even that they try to hinder me, like that as an NPC coach, these players to defeat them give you experience and part of your money, really, it would make the game more challenging, maybe it can be enabled by more experienced players and for new players can only enable it after completing the less a league. As I said by default the option would be disabled, and if it is the player's desire to enable and put that mode, I would seem an interaction of the most dynamic and attractive PVP, and as I said, without unbalancing levels, a guy with the same number of medals or perhaps a more or less that you can challenge, after fighting with someone will enable immunity / invisibility to your player so that no one can challenge you (For a short time), I do not even know to make it more attractive this could be implemented by using this mode and defeating players that hinder your adventure you gain triple the experience and money, it would be something worthwhile, at least for me and would make the adventure of experienced players more interesting.
