The first 6 star SMG, and oh boy, she deserves it. As long as the damage isn't so overwhelming that it can kill her dummies outright, she has a chance to negate the damage. The chances increase if the enemy has more debuffs or has Marks of Vengeance on them, which immediately makes her a good pair with M4. Also the Sop doll is cute and comes with weird features. This is literally Sop's fault.

The main feature of this mod is her multi-shot AoE grenades. Think FAL, basically. Also some buffs. Acceptable performance, but expensive for what she is.

For the massive expense of bothering to Mod her and get the second skill to lvl10, you get... a weaker molotov skill than Skorpion's at lvl1. Great?

On one hand, it has the same range as the flashbang grenade. On the other hand you paid the data, exp, and core costs for a Mod. Also, the firebomb goes off the same time as a flashbang, so it's slower than normal molotovs.

Yeah, honestly I forget she even existed.

With the advent of her mod, she goes from being Thompson's kouhai to one of the strongest force shielders available. Too bad G36c mod exists now, but let's not talk about her.

Through the power of milk, when she lowers her force shield, she gains a decent evasion buff to turn her into a mixed force shield and evasion tank. While the buff requires there to be multiple enemy packs, any amount of evasion to go along with the force shield is welcomed. Oh, did I mention she also buffs rifles with her tiles now? That's a thing. The buffs she does provide aren't particularly useful for rifles, but it may come in handy.

She DOES require her unique equipment from the night map to function effectively, for the milk tin is all powerful. The mod equipment, however, is pretty garbage.

On one hand, she's actually not bad, being a flashbang unit with a solid backup skill (If it's vs. a boss, she becomes a shielder tank instead with some minor evasion buffs) that also helps kill mooks faster. On the other hand, she has a mod3's price tag and opportunity cost, at a time when there's lots of nice mods running around.

If you already have a nice set of mod3 dolls, go ahead. If not, consider saving it for later.

...Oh, and you can save yourself the trouble of getting her mod equip. It's kinda pointless on a tank.

Her previous iteration can be found here

She gets debuffs that work even if the flashbang part of her skill doesn't, which makes her slightly more useful than a normal flashbang SMG. On the other hand, she's still a modded doll and thus expensive to build. She isn't useless, but justifying her cost when so many good mods exist that you'd want to get before her means that by the time you get her, she's probably not going to be your number one pick anyway.

Uh.... we came upon a weird timeline wherein frankly, if she had a +FP special item? She'd beat out Vector in a lot of cases. Now she only beats her in many cases and honestly might have more utility.

She learned to be less dumb with her tiles and actually they go BACKWARDS now. Wow. The buff percentages still aren't super impressive but she's no longer a dead slot for buffs. The damage she causes with that second skill? Surprisingly really high, especially in clusters. If lots of enemies are on fire next to each other, then they all affect each other with the burn, which can be really nasty vs some of the later ultra-dense enemy packs.

Aside from that, she's just a Molotov off-tank with an extra nice skill. She doesn't bring anything super new to the table as much as she's the pretty nice version of a dish you thought you'd never like.

So if it hasn't been said enough, absolutely get the Mod1 the very second you can. It's 200 fragments and some cores for a fair boost in performance. Extra stats, a bit more FP buff on her tiles, a little extra HP, and an improvement to the slowdown effect on the smoke.

The real problem is her 2nd skill is janky and not extremely practical. It's a little bit of a bonus, but not likely to make or break a fight. So yeah, the Mod2 isn't great. The mod 3 however, gives her a unique equipment that goes in the suppressor slot and is basically a suppressor with better stats (+5 EVA over normal) which helps her tanking ability somewhat. Whether this is worth it up to you, but definitely get the Mod1 at least.

The rest of this is basically the same song and dance where she has top class offensive buffs that continue to remain unmatched among SMGs, so you WILL likely continue to use her.
