I just got mine. Here are my specs First pilots AA Biggs Wedge 5's ashoka all max gear JC G10 Plo G9 Clone Sarge 6* G9 Poe G10. All L85
Ships all L73 save Biggs who is 80
I failed and failed until I had everyone up to 73 with all specials powered up.
Strategy
U need biggs to tank don't let biggs die early or u done for. Over sheilding with JC does not matter as
it gets blown away quickly with attacks anyway so even if he is near full i use jc to on him as i know he will be targeted
Kill Ashoka
Kill JC
Kill Rex
Then hit the rest of the clones. Go safety over gungho ie if u have Master
Plan hold it heal first or if u can kill one of thiers do that asap or they keep healing
