Kit Idea: Asajj Ventress (Bounty Hunter) Pls Check Out

I only have the wiki and the few episodes of the Clone Wars series to use as a reference for her character. Especially the wiki is a problem as that is more telling of "what" rather than "why". But I still think the core theme, as well as some minor things, don't fit her at all. First of all, the distinction between Dark Side and Light Sid allies. From what I can tell she didn't exactly treat others differently based on their alignment. She just completed the bounty unless it conflicted with her conscience. Most missions she even did solo. Thou obviously not all of them. She teamed up with Boba and his allies (multiple times), she helped Ahsoka, teamed up with Kenobi, and even helped the council try to take down Dooku. Even the mission we saw in the clone wars tv show, she didn't exactly go out of her way to make her allies fail in any way, and even went out of her way to pay them the part they owed. And that was at the start of her Bounty Hunting journey, when her alignment was still somewhat in question.
But that also brings the second thing: The entire "steal stats from allies and benefit from their defeat" theme. That doesn't fit her. As others have pointed out, she sacrificed herself to save Quinlan Vos's life. But if you take the theme in your kit, she should have weakened him, before watchin him fall, and them becoming stronger herself: Practically the exact opposite of what happened. Even going back to that mission with Boba and his syndicate we saw in the show: No one died, she didn't exactly become stronger as others fell out, and again, she brought them the share of the bounty they owed. Once again, not fitting a "weaken and ditch them" theme.
Finally, the unique doesn't fit her that much either. I mean, during her time as a bounty hunter, she actually started to mellow a bit. Even teaming up with those she previously wanted revenge with. If anything, she started to abandon the idea of taking revenge. Making your naming quite ironic. (Thou obviously not entirely, but it wasn't present enough anymore for an entire unique and status effect to be based on it in my opinion).
So yeah, this is why I don't like the core theme (and smaller revenge theme) of this kit.

This is the biggest practical problem of this kit. For starters, lets look at critical chance bonusses for Asajj in this kit: She gains additional critical chance on her basic, can steal massive amounts of critical chance with her first special, can gain critical chance up from her second special, can gain critical chance from the revenge buff, and can gain critical chance from defeated allies trough her payout. That's 5 sources trough which her critical chance can increase. There are also 4 critical damage increase sources, 4 offence increase sources, and 3 or 2 for practically ever other stat except speed. All for Asajj. I already didn't like the stealing stats theme, but this might also be the most overkill way of stacking stats I've seen in a long time. Seriously, I think SLKR doesn't gain stats as fast or massive as her. This is where the "Power for the sake of Power" feel comes from. Everything in this kit is just to increase her stats as much as possible, which I don't like.

Finally the 2 Zeta abilities. I wanted to address those separately as there are some things that I don't like about these specifically.
First the Ruthless Assassin special. The main problem here, is that it's way to easy for it to do nothing. What if she doesn't have any dark side Bounty Hunter allies and you don't have the zeta on this ability yet? Or if you use her solo? In both cases this ability does literally nothing, and they are not exactly difficult situations to set up. This is quite the design flaw that exists in this ability. Also, the damage from the zeta is really weird. Not only does it not specify to who it does damage (one enemy or multiple enemies. Weakest or strongest. Nothing is mentioned). But on what the damage is based is also really weird. I mean, what if SLKR is on the enemy team? Does the damage scale based on the stats he's takes as well? Cause that would make Asajj an absolutely broken counter to him. To be fair I don't think the game was ever even programmed to track and/or use stats in the way you described, but either way, that's just too much.
Then her Lead. While the zeta might be a tad too powerful (thou this is mostly due to its really weird max healing limit), its the "halve damage, double hit" and the contract that's really the problem. Cause even your extra explanation does nothing to help me understand how this ability works. Let's first look at it as you've put it down: "Use an ability that deals damage at least 16 times 5 times." Which I read as: "deal damage 16 times with a single ability, and do that 5 times in total" Which, taking into account the double hit from her lead, means an attack that damages 8 times. Which does not exist within the entire Bounty Hunter faction, including Asajj herself. The only ability that comes close is Boskk's assist. As with Jango, Boba, and Cad's basics all attacking twice, they can hit an enemy 8 times at max. But that's technically not a single ability, so that probably doesn't count given the wording. AoE's also only hit 6 times at max. So it seems like there's literally no way to complete this contract. But then comes your explanation of "So basically use 1 ability 4 times, then the next hits will count." Which doesn't really explain anything or make sense. Since a single ability dealing damage 1 time normally only makes 10 hits on the 5th use, not 16. But this also makes it seem like the contract is basically just "deal damage 40 times to enemies", just with 2 extra conditions that might make it the most difficult to achieve contract in the entire game. The "halve damage, double hit" effect also doesn't synergise with any part of her kit, or any other bounty hunter's for that matter. It might even be detrimental to many of their kits, if it doesn't break them. This effect and this contract are just "Complicated for the sake of being Complicated". The Contract even to the point that it might be impossible to achieve.
So yeah. Especially not a fan of these 2.
