Toons required to solo T7 rancor

Looking at your toons, with zeta Vader, you could easily do it with Darth Maul, Palp, Rex, & Dooku. TFP & Sid are ideal in place of Darth Maul & Dooku for tenacity down and DOT's but I see you only have TFP at 6* & Sid at 4*. So if you can't get TFP to 7* by the time you zeta Vader, I would run Dooku in his place. Just make sure you have omega'd Vader's "Force Crush" ability to inflict speed down and that you have a good amount of potency & speed on each character.

This was my run yesterday.
