What does your five TIE version look like?

Omega Leader (Juke, Comm Relay)

Howlrunner (Crack Shot)

Zeta Leader (Crack Shot)

Scourge (Crack Shot)

Youngster (Crack Shot)

With 12 dice (Zeta/Scourge) I hit as hard as 6 TIEs but with much higher PS I do it a lot earlier in the combat phase, which helps in a lot of head-up jousts (I'll back myself vs Brobots, for instance, which destroy a lot of swarms). And Omega Leader is waiting at the endgame to wrap up whatever is left.

It works.
