Oh boy, as a Shadow Caster lover (my favorite ship to fly, either Ketsu or Asajj tbh) I'm always up for discussing it and share a couple of lists I have with it, prepare for a big ramble, but i hope it helps or makes you think about possibilities.
I'll start with talking about Asajj and my preffered upgrades for her. The upgrade I always place on her is actually not on your list which is Hate. It's certainly overcosted at 9 points, and sometimes it might not be all that useful, but it allows you to constantly have force, if you take 1 damage it's 50% of her forces recovered, if you constantly evade with her (which is awesome that Shadow Casters have that action) dealing Asajj damage is stupidly difficult, because the damage you do deal, is just gonna help her fend off the next attack. There was a game where my opponent actually chose not to attack Asajj because he knew she was going to return just as much fire if he dealt damage.
I don't use Asajj's ability at every chance I get, because sometimes i just want to save that Force for a TL + 2 Forces Attack but it's great to just take out a token or stress someone if in a strategic situation, like after they've k-turned and have no tokens.
In most of my lists I try to keep her as slim as possible, so I just take hate (which sounds contradictory since it's 9 points of upgrades but usually worth it) but now that Shadow Caster title is 1 point, i don't really see a reason not to take it. Even if just to throw someone onto a rock.
Lattz makes her super hard to kill, but those 7 points aren't nearly as useful as the 9 points you pay for hate, while Lattz depends on matchup (if you don't have hate, you have to be careful with how you spend her force), hate is used pretty much every game. However if you have points for both, it's fun.
I once tried the combo HP + Title with Fenn Rau flying besides her and it's pretty fun and interesting, I did notice that you have to be alot more careful when using her force however, during that game, I don't think I used her ability once.
I have yet to try Maul on her, but it seems like it might be interesting, since she gets 3 force and a soft hate feature (if you just put hate on her it might be great but expensive).
Kiting with her agaisn't low agility ships is fine and works well. Agains't aces it's like trying to catch water with a net. I usually prefer jousting with her, as in shoot with the big front guns, specially since my action with her is usually TL for that sweet double modded shot. So yes, making lanes is very important when placing the rocks, it's also great fun when she can jump behind everyone with her 5K-turn and still have force mods.
When I take her I mostly take clouds, she's a big clunky ship and the chances of eating a rock can be high if not careful and one turn on top of an asteroid can be enough to lose a game, since she's probably an 80+ points investment. Even with the strain change I think they're worth it.
Now I have 3 lists I know work well since I've done retavely well with them in tournaments, only one is with the new points however:
Asajj Ventress (72)
Shadow Caster (1)
Ship total: 82 Half Points: 41 Threshold: 5
Ship total: 63 Half Points: 32 Threshold: 6
Prince Xizor (54)
Crack Shot (1)
Ship total: 55 Half Points: 28 Threshold: 3

This is the one that only works with the new points, and it looks super weird I know, but honestly it's hilarious to fly and I haven't lost a game with it yet (haven't had terrible dice with it yet but I did face a vulture swarm, I haven't played agaisn't aces but I think it's going to be this list's weak spot). The trick here is that they're all I4, so you have as much freedom as possible, and Bossk is the bait, people always go after him since he has greedo and hits like a truck, when in reality he's one of the weakest links in the list. Xizor is actually great for a I4 semi-ace, if you take out the higher initiative ships he can deal with the rest alone, and if people go after him he can just redirect damage to Bossk. Asajj is actually the most important ship in the list, she can offer control by stressing opponent's and tractoring them, allowing you to kind of reduce the downside of the YV-666 and I4 ships.
Asajj Ventress (72)
Ship total: 81 Half Points: 41 Threshold: 5
Old Teroch (56)
Ship total: 56 Half Points: 28 Threshold: 2
Advanced Sensors (10)
Mist Hunter (1)
Ship total: 60 Half Points: 30 Threshold: 5

This list was actually at 200 points before the change, and it might be worth putting the title on Asajj but I have yet to think too much about it (since I have Teroch a bit of bid wouldn't hurt either). This is probably one of my favorite Second Edition lists, while the previous list was all about damage, this list is mostly about control, while being able to lay down the hurt. I have managed to mutiply stress enemy ships (one time quadruply stressed an enemy asajj) and Teroch + Asajj is awesome because it takes out their choice of losing the tokens to take a stress, same goes for a block with 4-LOM, while him being stressed. There's so much you can do with this list and that's what makes it fun for me.
Asajj Ventress (72)

This one was before the points change as well so I got a few points (big few points). Out of all the 3 lists I'm showing here it's the one that least fits my playstyle, since I prefer to be aggressive and this list is more of the plink away and take none. Asajj is actually not super important here, but she ends up being really useful, in almost every game i played, everyone went for Asajj first, thinking they'd kill her off quickly and then deal with Guri, but if well played, Asajj can be really hard to kill, she can keep her distance or get evades at close range, and if the rocks are well placed (only list with which I took rocks), not having all your opponent's ships firing at the same time.
Well I could say more, but I think I've rambled on enough...
Sorry about the huge post, Asajj is one of my favorite pilots and there's so much you can discuss with her.
