Anyways, I suggest you to grind your IQ all the way up until you learn Pierce Hurler skill and take (or generate) a mission rewarding Lockon Specs. Hoard all Joy seeds and gummis you have that fits your partner, and go grind in the Final Maze. Group C focuses on endurance with strictly better offensive skills than group E (imbalance like this is why the group system was scrapped in DX). Group C can subsist on gummis alone for 48 floors to clear the maze, letting you grind both IQ and levels. Once you have Pierce Hurler, just throw all joy seeds and gummis you have at your partner and 2 teammates you like with lockon specs and you can skip so much grind that way.
