The wilderness is supposed to be dangerous, don't bring items you aren't prepared to lose. Before the update, a level 100 pker could have KO'ed him too. Sure, it may not always be fair, but thats the food chain for you. WOsh, wait a minute. This guy is probably like level 25 or something. How would a level 100 pker be able to attack him? Also, the pker would probably have enough respect to leave him alone.
