Seems pretty damned good for 18 points. Considering how useful the Crack Squadron or Crackshot Omega is, the few extra points for Mauler seems worth it.
In fact, I may amend my 3x Crack Squadron, 3x TIE/FO Crack list to sub in Mauler with Crackshot and potentially also Howlrunner with Crackshot.
Also, why not Mauler in general? Is it because Backstabber is thought to have the better ability? The awkwardness of having to fit 17 points into a build, the one point away from Howlrunner? His EPT slot not really being needed and EPTs just making him too expensive for a TIE Fighter?
Well with Crackshot, now that EPT slot is valuable. And at only a point it's not going to make him too expensive.
He's also decent with Whisper and Soontir if he has VI. Triple 9 PS.
