I sure as hell do! Grievous is somewhat of a Vader prototype and foreshadows what Anakin was doomed to become. It would have been an interesting battle with all that in mind. Sadly, one dumb line in Reveng of the Sith made such a match up imposible. At least we get Vader vs Karbin. That is as close to an Anakin vs Grievous fight we are ever going to get.
Throughout all of the history of Star Wars, canon and legends, who would you like to see get into a fight?
Me: Kir Kanos and Dash Rendar
