Depends on the team. You need tenacity down from somewhere (krennic or tfp) and tmr (zeta Vader leader is a must) Magmatrooper tarkin and thrawn work well too.
Tfp I'm currently running along with vader and tarkin, haven't zetad vader yet but am currently saving zetas for him, don't have magma so what two could fill my gap. Ep?
Without Zeta on vador it will be difficult, because the main TMR come from vador Zeta. EP will be a good 4th guy and another empire guy also. otherwise, you can choose Qui gon Jinn as a 5th guy with his quick strike he will add a TMR.

You will need decent speed with a toon like Jyn, or Thrawn.
CLS is a great addition, because he can basically do it himself.
TMR is key to rancor, so that is a always a good place to focus if solo is your goal. Zader and a solid team do it on auto, which is always my goal.
Zeta on vader's lead and thrawns unique, full auto if i recall correctly. It was a while back, see date on top.
