I'm sorry you had bad experiences in dungeons, while I haven't seen the name calling I experience impatient people in almost every dungeon. Anyone who resorts to that kind of name calling, id reccomend reporting them. Also maybe find a different fc if that guy was an officer, if not bring it up with one if its reoccurring.

If yer looking for hunts in the lower level areas, there should be hunt linkshells. Just shout in a major city a little and someone should invite you to one.
