How huge is the difference between 6*/7* Thrawn.

The gap between killing two death troopers and clearing the whole thing may be smaller than you think.

I'm still trying to get rng to work for me but my best run I've come into the final round dispelled a taunt killed a dt before second taunt and cleared the whole thing except for Ezra being on 95% tm and thrawn being on 100% tm both nearly out of health.
