Like every other DPS shotgun, she really doesn’t have a place in current content. A phrase commonly used around here is “a solution in search for a problem”, but the real problem with MAG-7 is that I’m not entirely sure she’s a solution either.

Her passive effect can be very nice when enemies start having 600 armor, but the times there are less than three targets are very rare. Her active skill can make her damage go sky high if it’s allowed to stack, but her being on the frontline gives her the same issues a lot of DPS SMGs have. She’ll lose links, cutting her damage by a ton. Not to mention that it takes a little while for it to ramp up. The DR afforded to her by the skill isn’t high enough to keep her healthy enough to do much.

Another one of those funny two-mode dolls. She's actually not an awful damage dealer, but her damage is still less than other dolls that are pure damage dealers. Also, despite having a rifle mode, she can't equip AP rounds so you're stuck with only the AP stats you get from her skill.

She might have use in some formations (mostly shenanigans), but most people probably won't use her.

On one hand, she's actually not bad in melee. On the other, she suffers from dumb mechanics (like not being able to switch to melee while reloading, which WOULD HAVE BEEN REALLY NICE). She's not terrible at the role of "melee shotgun" (she's actually quite good at it), but the number of situations where you'd actually want a melee shotgun are quite limited.
