I managed with Hera, chopper, zeb, Kanan and Ezra on,y Ezra gIX rest gVIII.
This was outlined in another post but I used 220spd on chopper and 195 in Ezra with the rest 125+
The trick is really to control the fight, don’t worry about pace or dmg just control
If you use only basic all the way to thrawn Ezra will have max stacks then try to take the first fracture on Kanan and use backup plan in whoever took it
Next cleanse the taunt, kill deathtroopers, cleanse taunt kill deathtroopers then magma save thrawn for last
I finished with full health and full prot on almost all
