Kanan at g9 will make things easy, especially with prot mods.
Zeb requires 60% potency. Else you will literally restart hundred of times till the debuff actually sticks. You will want to remove turnmeter on one deathtrooper and stick daze on Thrawn.
Zeb doesnt need g9, as he is a tank without damage (unless zeta'd).
50 - 60 speed mods on ezra/hera and chopper fastest (has high base speed) and its a fly through. I have done it with 76 w/o any omegas and skill mix 3-6. You will do it! :)
