Finally 3 starred it.
Borrowed old Ben, wedge lead, Biggs, lando, sthan, Akbar.
First round had 3 of the aoe light clothes guys. All 3 didn't do their aoe and two of them I dodged. Second round 1 x 86, 2 x light clothes Aoe and 1 x dark aoe dude. With tm built up I was able to take all of them out except one who did their basic attack for minimal damage. So far amazing rng and made sure I saved all special moves. Last round I used old Ben debuff first move. All ability blocked except embo. Then Akbar went gave 2 x attacks for lando. Then wedge aoe. Then wiggs destroyed the only sabatour that wasn't ability blocked. Then sthan taunted. Embo put death mark on but next in line was Akbar to cleanse it. A few weak basic attacks on sthan then more tm gain meant lando went against and then Biggs and wedge mopped up.
I had amazing rng and good luck with dodges with old Ben. But I must have attempted it 40-50 times. Was worth it though. So satisfying and soon I'll have my shore trooper :)
