All the accuracy ever. There's not very much practical use for it still, but she converts excess accuracy to crit now. This does not push her damage up beyond the really good ARs, but some of you might get creative with it.

Can she dethrone AS Val's ridiculously solidified position as a top-tier damage dealer? ...Not really. She suffers from wanting some base crit rate, but making use of her crit rate requires either targets with shit evasion to begin with, a ridiculously high hit rate modifier somehow, or some other means of hitting targets at night. She might have some uses, but she's harder to use than AS Val, and you don't get much in exchange for it.

Her Mod 3 unique equip is alright. It lets her punch through lighter armors, and otherwise is excellent at finishing off weakened enemies, rather than wasting full-power shots on them. This is usually a thing with rifles that don't quite instantly giblet their foes. Her tile buffs are pretty okay.

She's alright but not a priority.

Okay so maybe China doesn't ABSOLUTELY hate Taiwan? Or else this gun wouldn't have stats literally on par with (or in many cases better than) actual 5 star ARs. She actually outdamages T91 during the day flat out. At night she's a super budget option that won't match 9A91 or any of the better ones, but at least she's cheap. She does however suffer from being a login doll, but she becomes permanently farmable later. Tile buffs are surprisingly alright for a free login doll.

Really a budget option, but at least one that isn't awful.

Gao.

The first DPS handgun that actually produces well.. actual dps. Also might have possibly gotten lost from Kancolle.

Her skill gives her doubleshot and 100% crit rate while active, which is surprisingly strong on a handgun. Dont knock it.

Great as the damage dealer for 5HG teams, or a variety of misc. uses since she actually has alright tiles too. While she's not super impressive during the day (especially compared to good ARs), she shines at night due to being able to pack 100% crit rate while equipped with a PEQ.

Her main disadvantage is what a pain in the ass she is to get, since you need the first 5 volumes of the Comic in the Cafe. Her special costume requires the other 5. This is a heap of batteries.

She's pretty decent though, so it's not exactly a waste to do it.

She also has a mod, and the review for that can be found here.
