[Star Wars ROTS] The opening text mention "heroes on both sides" who were the heroes on the side of the Separatists?

Basically all of them. 

They were fighting against a corrupt inefficent government that allowed Jedi, religious warriors to subvert the whole system whenever they wanted and never get punished. 

If you want specifics, I'd go with Count Dooku, Mand'alor Spar, and the countless clone deserters.
