Even if she sucked, most of you degens would go after her anyway. Thankfully, she's actually pretty good.

Not quite in the same vein as SAT8, as she only shields herself, but the damage reduction effect allows her and allies to tank a bit harder against shots that exceed her armour value, and yes, that applies to shots that ignore armour outright. So basically if she's on the forward center, then positions 4, 5, and 6 benefit from the DR, and so on.

Because of her passive and the 3 second ICD on her skill, she actually has really good uptime overall (similar to but slightly worse than SAT8), and yes, she can be made to pop her shield more often via shooting faster and going into reload faster (though this can produce an odd gap in uptime past the 13s mark).

G&K's equal opportunity things means even penguins are accepted, I guess. She has a finnicky, slow, and generally not reliable shield. On the other hand, her gimmick relies on having shields.

She relies quite heavily on outside shields if you want to use her gimmick, so stuff like SAT8 and LWMMG mod will come in handy if you want to do so.

However, while she has good armour, her HP is the worst of the 5 star shotguns, and she doesn't have particularly good tanking gimmicks. She's usable, but probably wont be your first choice unless you want to use her gimmick that badly for whatever fucking reason
