Good question! I don't know names, but I still see good stories coming from Capcom's games, so they still have good people there. We don't know if Bingo was good or bad , in the sense Capcom's superiors meddle too much in team's affairs ( Kamiya complained about it too): we just know Bingo had a extensive story written for DMC4 and someone ( one of his bosses, I suppose) just butchered it. Kobayashi is not innocent of this too.
About a dull Dante in anime:
DMC1 novel describes Dante as being serious, philosophical, loner and calm, his one liners and that "devil may care attitude" was only a facade for making him felt at ease. People like to think Dante is some kind of a Ninja Turtle, but he isn't.
Taking into account Anime used some parts of that novel, the Dante we see in anime is his real "me".
