T5&6 I end up using CLS, Han, Chewie, Dooku, and maybe Palp. T7 I did put 3PO in for Palp. Key was to just kill off Mando, then don't kill Cara unless she has potency up so you get more stun attempts.
T1 and 2 took a very long time but I found something that works. G8 Aayla lead with offense square off, zBarriss with offense square off, g6 RG with lots of speed. T2 I put the mods back on and threw in BB-8 and Hoda. Obviously Hoda just heals RG or calls assists if necessary. BB-8 was just there in case I needed more offense cleaning up, but I didn't. Just did his little roll thing.
