A random group of people last night wanted my help with a normal vault of glass run through. (I'm a 32 warlock btw) I obliged. I ran through it with only five people and helped them do their first and fastest run through. They freaked out at the end since they haven't beat it before and they were getting legendary gear. I got the last word exotic hand cannon. So the time I spent teaching new players didn't let me down. Don't be a douche and not join people just because your a high level. You can be rewarded for your time. :)
