I don't get why there are people who queue for group content of any kind and play as if they don't care much and don't want to be accountable for their level of play. If you don't care and only want to half-ass your performance you shouldn't queue into any group content until you are willing to be fully committed to play at a good level. If you aren't as knowledgeable with the job you want to play yet, then go research and ask for advice and get some practice in to improve. When you queue for something put your good effort in as you would want the same from the rest of the party members.
