2nd EDITION, obviously
With second edition bringing a few noteworthy arcdodgers and token stackers (from the humble fel/whisper to the mighty Lord Vader himself), I feel it's best to start familiarizing ourselves with this humble but potent ace/Jedi huntress
Kestal benefits from the incredible arc coverage of primary arc + turret. And thanks to barrage rockets, her front arc is actually worth a ****!
Imo, her default build is
(36) Lieutenant Kestal
(6) Barrage Rockets
(1) Ruthless
(6) Ion Cannon Turret
Points 49
That's 24/25 points in 1st Ed terms, ie VERY tolerable given how squishy the TIE/aggressor is
The secret to utilizing Kestal (other than keeping her on the flank and outside direct engagement) is to give her enough mods to allow her to spend her focus in her ability. This is accomplished via Ruthless and Jonus.
Yes, TIE Bombers are great with basically everyone (because they ******* rock), but since the TIE/ag could basically be its cousin it's very easy to integrate into bomber formations
Bombers also have the dubious honor of being incredible Ruthless targets. Plus, given how clunky they can be (despite essential dial improvements...thank FFG for that white 2-turn) they really benefit from an ace hunter like Kestal. Be aggressive with ruthless, because non-jonus bombers ain't great late game.
because of her cost, she's easy to include in lists
Her, Barrage Jonus, and THREE barrage scimitars will run you 197 points (200 if elusive on Jonus)
Her, Barrage Jonus with Elusive, Barrage Rhymer with Elusive + adv protons, all aided by Palp on a scariff base pilot = 197 points
....so yeah, be aware she exists when you start running into Fels/whispers/any manner of force user/moldy crows (just not Palob, sadly)
