Devil May Cry already has its brutal aspects in combat.
Devil May Cry does have a story and even DMC4 was driven by its story that we had to play as a newcomer Nero more over Dante mainly because Dante's story is over(DMC1 was the middle, DMC2 was the end, & DCM3 was the beginning of Dante's story). Capcom did a smart thing and focused on a new character(in DMC4) for the SAKE OF THE STORY if it was Dante again. Capcom like many game companies know that nowadays a series continuation is a balance of its gameplay mechanics/features and story. You can't continue a game series if there is no sensible way to continue the story or anyway to further the gameplay or improve it to ensure a new game experience(meaning if you did everything already whatelse can you add).
Plus this Dante's fighting style isn't nearly as brutal as Nero's fighting style......and if your complaining about Capcom sacrificing Stylish action for Brutality Capcom already did that long ago(DMC4).
