The doll is basically Spitfire with slightly different buff tile layout/focus (less FP, more Acc). Frankly, she's really boring statwise and enemy RoF reduction is usually worse than FP reduction (which is good for armor/shield tanking) or acc reduction (Which is good for Eva tanking) and the Spitfire entry has the rest of my thoughts on that.

She thinks of herself as an elite doll, due to the P226's previous adoption by the US Navy SEALs (hence the Seal she has with her) and has a bit of a rivalry with M9, claiming she should absolutely be the more popular one. More info on the notes.

A Britbong copy of Cz-75! ...And kinda weird. She's sort of setup for the 2MG 2SG 1HG thing that doesn't come up much and is defensively oriented, but sometimes it comes up. Just... not on any content currently. Does occasionally see actual use as a result, but she's not going to be your first pick for most jobs.

The problem is that RoF reduction is kinda meh, as while it does reduce enemy DPS, it merely slows down the rate of being shot, as opposed to making shots worse (good for SGs as their armour can more readily absorb it) or less accurate (which helps Eva tanks just not be damaged entirely), making it the weakest of the enemy attack stat debuffs.
