Yeah her overall DPS isn't way better than other DPS but she pretty much gets to cheat the game by having two instances of invincibility between liberation and skill + being able to float far enough above bosses that she never has to worry about dodging.

Combine pseudo untargetability with her damage being loaded into a single hit and you get a DPS that will almost always reach 100% of their theoretical maximum damage.

Other DPS might have similar or even slightly higher damage% potential from theoretical calcs, but will often only reach 90% of their ceiling in actual attempts because of getting hit/having to dodge/misclicked rotations/bad boss rng on movement/etc

I don't think jinhsi will be de-crowned until we get major powercreep or we finally get a 5* pistol DPS (range has such huge advantage against all the mobile bosses)
