Trying to figure out Solo Rancor team...

You don't need other toons. You need to use less. Leia and OB aren't adding anything, and Leia is actually making it harder with the multiple attacks generating TM. You could probably get by with Teebo lead, CLS, and R2. Or you could do Wiggs, CLS, and QGJ (could be Han or Rex etc., but you have QGJ). Adding in more characters that don't remove TM or cause Rancor to generate more TM than you can adequately handles is counterproductive.
