Within the span of about a half an hour, Chya was attacked by three different characters. Why? Because they thought they could play the pvp part of this game. And that is the game of course. So you get mid level and decide to try and take out someone weaker than you because it's your turn. Either way, the random pvp has probably caused some people to not want to play.
In this scenario the pvp'ers died every single time, but this isn't always the case. Being mid-level is dangerous because people can and will randomly attack you.
