Yeah CC nin is more about using ranged during chase or the opening salvo. If you're quick you can actually pull off almost a full K.O. by using bunshin->Huton->Assassinate(12,000+6000)->Mug(2,000)->Hyosho Ranryu(17,600)-> mop up with fuma for 9,000 a pop. This doesn't really work once people see it once, but it's good for first match of the day with someone or during tense moments. Other than that you get a ton more damage output from using weapon skill combo and raiju with bunshin since Assassinate and Fuma are always halved.
