I presume you have done BOTH debuffs. The one without quest AND the one with quest (KO03)

I dont know, I also did E3 Normal, my comp is almost similar as yours.

My total sortie to E3 is 28, (Including farming) I only mnage to kill the Twin Abyssal Boss ONCE (luckily is during last dance.)

That time was really lucky, all 5 cut-in procced and ALL targetted  the boss and ignored the other 2 ships.

Right now I am farming the Boss node, the closest i got was getting the boss to red health twice >.<

Sorry, I cant help, I can only encourage you to not give up.
