The change of artist did her a world of good. She went from kind of cute to straight up hot. Too bad your waifu still sucks. She isn't the shittiest shotgun in the game, but her mod's not exactly groundbreaking. The decrease in enemy movement speed is almost an afterthought since it lasts one second and she has a very low rate of fire making the skill questionable at best. If the duration were longer and knockback didn't have such a low chance to go off maybe it'd be better, but alas.

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.

Supernova is a shotgun pretending to be a handgun to go along with her shipmate GSh-18. She’s one of the most supportive shotguns available and she enables some real dumb stuff. You want to use MGs at night? Well, her skill allows for that. Do you need a little more defensive capability for your shotguns? She brings that too, all in a kancolle-flavoured package. Honestly, she’s not an automatic pick on every team. You’re likely going to have to drop a MG in your formation to make use of her fully, which can be an issue.

Her two main draws are her movement speed and her MG buffs. Her roller skates allow her to go almost as fast as a handgun, but not quite. Not much else to say about that, but main reason to take her is the MG buffs she provides.

While crit rate is nice, the accuracy buff she provides to MGs is fixed. This means that MGs are entirely usable at night. It bypasses the accuracy penalty that you would normally have with no PEQ. While not the most relevant thing currently, you definitely want to have Supernova in your back pocket for the future.

Oh hey. DPS shotgun. Like every other DPS shotgun, she has the issue of “when would this even be relevant?” So, I’m not going to focus on that.

The main eye-catching bit of her skill is the instant kill shot once she hits 100 stacks. While useful, it only happens once per battle, so you can’t rely on it. Her real strength comes from her having perfect accuracy, higher knockback chance, and no need to reload. This can make her an absolute monster when knockback is desired.

The problem with this comes with the constraints that you need to follow to really get her going. First, you need another shotgun with her, which isn’t terribly difficult. Next, you need to have her hit 100 stacks. You get one per hit on an enemy, which may sound like a lot, but it isn’t. This takes into account dummy links, as well as the fact that shotguns hit multiple enemies, so you can get up to 25 stacks per shot. (Assuming you’re using bird shot, which you should be using) It’s entirely feasible to get 100 stacks in one of her mags. However, this can be an issue in battles with lower enemy count, which will hamper her stack gains.

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.
