with the landing 100 yards away thing... some of it is hard because i can't quite get an accurate scale for how big that ship is, but it shows the ship getting close enough for the spotlight to hit pretty bright, which ultimately scares shin off. then it shows ahsoka running from what seems to be roughly 20 yards or so? and while it doesn't quite jive with what we've seen them do in the cartoons, like you said jumping from ship to ship and then landing a 300ft jump, i feel like the more they lean into stuff like that, the more silly it would look. it looks great in stylistic cartoons but not so great in live action. i mean in normal clone wars episodes, ahsoka is doing triple spin backflips from a standing position all while deflecting blaster shots mid air. humans can't do that so trying to do that in live action just invites criticism.
and with sabine not being force sensitive... i think there's a difference between "force sensitive" and being sensitive enough to train as a jedi. and with huyang basically telling her that in ALL his years he's never seen a padawan with LESS force sensitivity as sabine, doesn't interfere at all with why kanan and bendu never remarked at her force sensitivity.
i very much got the impression that she wasn't being trained LIKE a jedi, per se, because there's just a ton of things that she won't be able to do. but rather, she's being trained AS a jedi. so more the knowledge and philosophy aspects of things. i mean, you could argue that only jedi and sith can effectively use lightsabers, that's only true... from a certain point of view =D
someone who's able to use the force will have a bit of precognition and can use that to aid in fighting/deflecting blaster bolts, but there are all kinds of humans on earth who are/were brilliant at swordplay. she'd be at a DISTINCT disadvantage against a force user, but we saw what happens when she went up against one. shin was just toying with her the entire time.
