Tier 5 of maces ship challenge is impossible.

I ended up using one reinforcement. You really do need them. I was 5* at the time. RNG, and Republic ships is how I went. I felt that Rex was key for me. Kept me alive long enough to continue to pummel with Mace, JC, CS and 5's also helped me stay alive. Biggs was starting too but he didn't last long. Sent in Ahsoka to replace and finished with Ahsoka and 5's dead.
