You should make an effort to read up on the fights online before you go in. It takes all of 2 minutes and it's inconsiderate to go in with no knowledge of a fight. Sure if you have questions people should answer them and help out where they can. But not familiarizing yourself with the dungeon bosses before hand is just selfish and lazy. There are more people in the group than just you and being prepared when you're new will get you much more respect. If you put in a bit of work beforehand, people are far more willing to help out. But if you do nothing at all, why should we? Give and take - you can't expect other people to do all the work for you.
