Nah man old Vergil got slapped around by old Dante plenty but new Vergil was never a legitimate threat (ie. not menacing) and wasn't motivated enough.New Vergil is best Vergil. Dahbomb is just mad because he got slapped down by Donte. Come at me.
By the time you end the Vergil DLC you are aching for that Dante/Vergil rematch. So yea I felt it did a better job of developing Vergil's character than the main game.
