When you think about it we have hardly seen any true Separatists on TCW since Dooku was just going along with his Sidous's plan, Grievous was only in the war because of his hatred for Jedi and the CIS Council Leaders/Corporation Leaders Nute Gunray and Wat Tambor only seemed to be bothered about profits (apart from Gunray wanting revenge on Padme) and just committed crimes under the Separatists name. The CIS commanders were just shown to be evil. We hardly had any characters that seemed to be truly bothered about the Separatist Cause, the only two I could be sure were true Separatists are Mina and Lux Bonteri. We needed to see some Separatists that were fueled by rage towards the Republic. There should have been more episodes exploring the Separatists, I am left with questions such as why did so many Separatists dislike the Republic? What did they think of Corporations such as the Trade Federation and Banking Clan doing business with Republic as well thus keeping the war going? What did they think of the Leaders of such Corporations being on the Separatist Council? The way I see it is that villains like Dooku and Gunray just wanted to be labelled as Separatists and were labelled as Separatists, but weren't true Separatists. Heroes on Both Sides was the best episode we got for exploring the Separatists.
