C3PO unlock and 7*

I got 7* after about a dozen tries. All gXI, all 4 Zetas, and Elder as the 5th. Speed was no factor as my fastest is 167? Elder seemed to be key to recover after the initial volley (beatdown). After that patience was key. It was mostly just a matter of hoping that I lost no more than one (not Elder) in the first set of attacks. Paploo is way more important than people give credit for. Him getting retribution and stripping buffs was huge. On the final run, I took out the trooper, then Chewbacca, then Han, R2, Leia, last 3po. Finished 3*
