9 out of 10 times you have no problems to finish a dungeon with 4 people, even with bad gear... Just ignore that people and finish your run without bi tching about it. Most of my runs are without problems and extremly smooth. i would say, that not even 10% of my runs get wasted by stupid people, mostly because i simply ignore them and move on. I would love to punish all this disbehaving people, but actualy this would only leave me with not a single finished rdf hc.
