Unleash the blood
Well that's dangerous thinking chief. Refusing to increase the roster and over-reliance on tested concepts is the fast track to stagnation. If you keep the same basic character abilities and just throw on a gimmick now and then, you're left with Modern Warfare.
Well, Dante didn't have the same basic abilities, his new moveset allowed access to all his styles at once, plus new weapons. It took combat to the next level while still allowing for familiarity; you don't want the old moves completely switched out, just evolved. The Devil Bringer was part of that evolution, and if it was fluidly combined with Dante's moveset and set against a broader selection of maps and dynamic bosses, with a tighter story to bind it all together, I think it would have been anything but stagnant. Sequels have to try new things without abandoning the old, otherwise you might as well just make a new IP.
Imagine if they had been a bit more ambitious with the cast, bringing in radically new personas and fighting styles, characters with wildly different gameplay. Hell, I though they were leading up to that with the way that the Devil May Cry agency had expanded by DMC4.
Yeah, the lack of unique costumes in DMC4 was almost painful. Getting to play as a properly differentiated Nero, Lady, or Credo, with their wild movesets and just enough adjustment to the maps, enemies, and story to make their (probably much shorter by necessity) paths different from Dante's main story would have been amazing.
