Easy DTMG (Dark Trooper Moff Gideon) 3* in Proving Grounds
GLeia, CRex, R2, Drogan, CLS. Keep DTMG stunned as much as possible, pass around other stuns, then defeat everyone but DTMG first.
Forum Discussion
I found Darth Malgus, Darth Revan. Malak, Fallen Bastila and Darth Talon can 7 star it. Gotta keep DTMG under fear and poc off everyone else starting with the scout trooper
