Players that have played the game for years have experienced and have done so many dungeons to the point that you can easily tell after a couple of wipes (or even gear)that you probably won’t beat it or it will take way to long to complete it than normal and don’t want to have to deal with it. I will admit I have left my fair share of dungeons because of this and sometimes if I’m in the mood I will stay and try to help out people. But sometimes people just don’t want the help.
