I beat it today - took 4 attempts. first 2 got to a 1v1 situation. 3rd they blew my wedge away without a move so retreated and 4th time ended up with a 5v1 so couldnt lose. Agree with above. where possible heal heal heal.
I had only 6 ships. Wedge, Biggs, 5's, jedi cons, tano and resistance pilot (reserve). Defeat there tano first, then jc, then rex and then clones as mentioned above. I was lucky on last attempt as they did only 2 reinforcements - 1 being a jedi cons and the other clones. Been trying casually for last few weeks and didnt ever get as close as i did today.
