Grace and Glory are the Dodge-Offset tutorial. I had a hard time with them at first but it helped me prioritize which strings to use and when before that. Only certain attacks trigger Witch Time, depending on the difficulty setting. Their EX-versions don't trigger Witch Time at all.
I'd argue the fire enemies in chapter 3 are the tutorial first though.
On topic: The Fallen , and the bolt shooters in DMC3 are my least favorite it to fight. Nothing satisfying about beating them and they don't bring anything to the game.
Arrow shooters and the flying dragons in NG2 were annoying as well.
