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.

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.
