Except what is shown in cutscenes doesn't really deviate from what's possible in-game. Furthermore, any game worth its salt, and I do hold DMC in very high regards, lets you have gameplay power that is roughly equivalent to what's possible in cutscenes. DMC shows Dante flipping around and surfing enemies, and sure enough, those are things you can do once it hands control over.

While we're at it, even cutscenes depict mooks as... mooks. They get torn up no problem. This RP is based on three different settings about tearing apart nameless enemies, and the six grunts fit that description pretty well.

Furthermore, what, to you, makes a Devil Arm stronger? Their inherent qualities are high durability (but not indestructibility, as evidenced by Yamato, a high-tier weapon) and generally some sort of magical property. For example, Ifrit is on fire and Nevan can shoot lightning blasts. But even Rebellion, Dante's mainstay, is for all intents and purposes just a claymore.
Also, how does one create artificial Devil Arms? Do you have artificial souls lying around? How are those created and what makes it more convenient than just developing better gun technology? Kalina Ann is mundane and it gets the job done with flying colors.
