Treybert nailed it for me. Just because Juno can't turn 90° and then Boost another 45° doesn't make her useless; it just means she's not Fel. Instead, she often has a greater base damage with ATC, never mind the impact (psychological or otherwise) of a crit on every attack, plus she has greater resilience due to the TIE/ad shielding and equal agility, plus plus PtL token turtling. And then, on top of all of that, she doesn't waste a Mod slot on the Targeting Computer; most of us feel more comfortable giving Fel a Shield or Stealth alongside 'Thrusters, right? Never mind the slow-roll approach of 1-Bank, BR, then TL/Focus/Evade as needed.
Being able to 3-Bank or 1-Straight to drop stress feels great, and even then Juno being able to change speed makes her drastically better than an Interceptor for me. Her damage is fine, she's harder to force into a bump, and since she doesn't always have to Push and stress, her 4-K (or 3, or 5) makes her solid enough at jousting (and then recovering from the K-Turn, again, she's got options upon options). I think she's going to be a nimble, persistent, evasive powerhouse. I can't wait.
But, Sekac, you're listing an awful lot of corner cases where for some reason she isn't able to have a Target Lock in effect. Bumping is the easy one: dial back her speed or shoot past. Done. Overshooting your enemies? That's hardly an issue; take a TL and come around for the next approach. There's no need for you to use both actions and not TL if you have a shot (if you're going to say Barrel Roll and Evade, it's kind of one or the other: BR out of arc, and if you can't then take the Evade). A shot of opportunity on a higher PS ship? What, did Fel somehow park himself in front of you? Always take the stronger shot, no matter how tempting a "chance" shot may be. Shoot at Fel if you've already got a TL on Fel (which you totally should! Approach Fel by making it impossible for him to take a shot at you, TL, and then watch him BR/Boost out of arc, but then you don't need to take the TL ever again). Finally, PtL doesn't limit her ability whatsoever if you know when to Push and when to hold off. Fel is a terrible way to learn how to PtL because he can turn 135° in a round and gets a third token for the stress; he does it every opportunity he gets. Someone like Juno will make that call turn-to-turn. PS8 isn't exactly a bad place to be for that!
