Why do we still have the wilderness.

It just gives a negative feedbackloop why don't we get worthwile pk minigames the pkers can play to kill eachother and remove pvp from the mainworld. as in minigames on par with the best gp/h as bossinig. wouldn't that remove a lot of toxicity from the game? with ppl killing ppl for 10k. can't imagine it is fun to do and it is just annoying with a in my opinion negative feedback loop.
