My big issue is I use the duty finder for higher level content and get people who don't know their roles and how to fulfill them, bad gear (having anything below level 40-45 on while in a 50 dungeon is bad gear), and seem to have no communication skills, by some standards that is all fine and dandy. I lose my patience at said group because they are being idiots, I'm suddenly an elitist abusing the DF. Fact is I'm not going to teach player a class at level 50, I'm not going to teach them basic mechanics. I will teach how a dungeon works though, and how I do said dungeon. My tolerance for stupidity is low, my tolerance for learning is high. Though I have no issue if you use duty finder and drop out because you don't want to teach 3 others how to run a dungeon for the first time either. That can be tough without voice.
