I like your suggestion for swords, but I have to disagree with you on the role of aggressive shotguns. I see them more as raw damage type weapons due to the fact that they are extremely clunky, but generally have more and better damage perks than other frames, and usually not many utility or crowd control perks. They deal more damage per shot than slugs, but less than High-Impact Fusions, which have a marginally faster fire rate (even with assault mag), which is why I believe Bungo should just lean into the high risk/reward factor and allow them to do very high burst damage above all else

I don't mean to sound rude (not my goal) Aggressive shotguns tend to be the least burst-damage oriented shotguns out of the available frames. Rather, they display a unique property of being able to fire their full reserves at maximum fire rate, thus making them a little more sustained-damage. Rapid-fires, on the other paw, show great burst damage when accounting for dumping their magazine. They suffer long term due to reloading (which can be mitigated). This is kind of reversed in ad clear scenarios. The high damage, single shot of aggressive can chunk majors, and the intrinsic trait helps keep them, well, aggressive. They are limited by their lower magazine sizes, and sometimes reserves. Rapid fires, which reload each shell faster, can sustain adclear small ads with more efficiency, however, with less efficacy against majors (taking more shots, requires longer reload). I feel as if a magazine bump and a specialized perk pool on a new aggressive shotgun could do the frame justice. This is coming from someone who used a toil and trouble (field prep, autoloading) for several hundred pve kills. (This is also not me saying your idea bad! I'm offering a my own opinion.)
