Whether they will bring back V somehow (I think it's best done as an unlockable non story related costume for Vergil, kinda like Nelo Angelo in DMC3) or make another character with his playstyle, I want them to improve the responsiveness of the familiars. The melee one specifically needs either to have longer engagement radius (from where V is) or it has to follow V closely all the time so that you have actual control over its location at all times. Or they could make it so that when you lock onto someone, it immediately teleports over there.
Also the dodges need to be untied from the familiars, or at least tied to another separate one that doesn't fight but it's only for dodging, which could open possibilities for upgrades, like Nero's Table Hopper or Dante's dashes. Cause as it stands now in DMC5, dodging resets the familiars's position onto yours, which in the case of Shadow is a problem cause before you can even think about re-engaging immediately as you would with Nero or Dante, you have to wait for it to run to the enemy on its own. That creates downtime, and disrupts the flow of combat. Such downtime could easily be reduced by doing what I described here and/or the previous paragraph.
I feel like V's playstyle is unique and interesting, but I found it a bit clunky and unintuitive for those reasons. Very satisfying when it works fluidly, but they need to work on making the fluidity consistent. In my opinion. I know a lot of people love his gameplay as it is now, yet I've seen just as many people sharing my complaints. He's not unplayable or unfun by any means, but rough around the edges enough that he feels less satisfying than Nero and Dante. It's the first time they tried something like this so I can understand but still. There's room for improvement.
