You want safe (as in no interference) 1v1? Campaign for a "duel to the death" option in addition to the standard duels we have now. You win, you get to loot.
Yeah that isn't true at all. Runescape has non-instanced forced 1v1s. Did you even read what I wrote? You act like it's not possible to do in an open world game and yet a game that is 18 years old has it.
