enh, not so much. How could anyone pk, if every pvp fight was optional? It would be more like dueling, only minus staking as well. It would be a good minigame, so people who only fun in the dueling arena wouldn't be mixed in with all the stakers, like if two people could just fight eachother and say boom, i win, or boom, you win, and forget about it. Perhaps as a minigame one could get points, like at cw, for each won fight, and trade them in for some reward, so there would be a reason to win...
