oh yeah I was a little bored since there is this map somewhere at level 130+ that there is so many people and since I was too lazy to run around … I then just make my quest fail in purpose to grind.
yeah the quest that tells you to wada wada in x time limit… all you need is fail it. and talk to npc again and again and again and again… grind that spot until you are happy nobody will steal mobs on you since you are alone… and you will be sure that there is always lots of mob in x seconds.
