Quite true. I was mostly thinking in a particular, characteristic ability: swordsmanship was Dooku´s thing indeed, but it was also Maul´s... and then again, Sidious was shown to be an even better swordsman than both of them! What I had in mind was something like Jerec´s long list of particular abilities, like the one called "Force destruction", his ability to see through the Force, or to dampen the Force connection of others. This last one was the one Hethrir was particularly known for... so I missed in Dooku a little something that was an expression of his own particular connection with the Force. He made a great political leader, nonetheless. That´s an amazing ability. In Legends, didn´t he use Jeng Droga as a vessel after Endor?
