Some notes about speed and turn order. Ideal speed order is CLS > Han > R2 > Chewie > 3PO. The reason Han faster than R2 is because this way Han can use Deadeye before R2 use Smoke Screen and either his basic or Show me the Odds without lose stealth; 3PO last to allow the rest of the team to gain at least one stack of Translation and so be called to assist with Oh My Goodness!. Try to get 20-30 speed difference between each other, this to avoid 2 or more characters to gain 100% TM due to TM gain (in which case it's random who takes the turn first). Mods priority:
*CLS: Speed > Offense/Potency (the fastest character
*Han: CD (set and triangle) > Speed > CC
*R2: Health/Tenacity > Speed (3 Health sets works)
*Chewbacca: Offense > CD (triangle at least)
*3PO: Potency > Health/Protection (enough to grant CLS the guard buff from Chewie)
