Dark Side 4+ missions

Ravage

How are you all 3*ing missions on dark side. I can't seem to keep up with the amount of AOE damage and healing as dark side.

I have 4* Doku, 4* ig88, 5* talis, 4* darth maul and 4* tarkin

Dark 4 L boss is insane. My toons are now at level 48 with level 5 or 6 gears, yet she always managed to steal at least one.
