If there's any way to get Chopper up to speed in time I recommend putting him in there instead of Sabine. There are two reasons. One is his dispel. Depending on turn meter, you'll need either Ezra or Chop to dispel the taunting Stormtrooper at the very beginning of the round. Then whoever didn't use their dispel on the Trooper can use theirs on one of the Deathtroopers. You can get Kanan to Taunt and absorb the Fracture, then just use Chopper to Taunt after that. Use Hera's special on whoever gets fractured so that they come back to life. Keep giving protection up to each other, rotate taunts between Kanan and Chopper, and just whittle away. Kill order has already been stated many times, and I think it's spot on.
