I was level 29, and went to the forums to ask for help with my first Nightfall. A couple of lvl 31's invited me to their group and said they wouldn't mind pulling me through. I must have died 10 or so times, and had half the kills of anyone else. We finished in pretty good time despite me being carried. At the end, I started to thank them for taking me through, and the next thing you know they're swearing and saying this game sucks, and they rage quit the group... I got the Ghorn as a reward. Really, I felt awful... but that soon wore off, haha.
