Max level people get paired with low level people all the time. There are many people that run 6-10 roulettes per day. And yeah, a few of them require level 60 and the main story being done/close to. But many of them are designed to get high level people doing lower level content so that lower level people get the help they need to get through(leveling, main scen, mentor, and trials in particular). If i que leveling roulette, i expect to be matched with people lower level then me who have(often poor quality) level appropriate gear and possibly not a full grasp on how their class should be played. So why would i still que? Sometimes to help people, sometimes for tomes, usually because im leveling up something and want that sweet bonus exp. If you really feel self conscious about it, do some practice runs with lower level content. Did you clear all 17 level 50 dungeons to open up the lvl 50 roulette? If not, do one or two of them to get a feel for your class again. You can tell the people in your group at the beginning that youre new to the dungeon/a returning player. After a few runs youll be ready to hop back into the aery(lvl 55 story dungeon youre probly getting to soonish) and continue on with the story.
