A Naruto series without Susanoo? Oh you mean like how it was before the Sasuke VS Itachi fight? Give me a break people, I don't know why some of you act like Naruto couldn't exist without this OP jutsu. In my opinion it was alot better before people started hiding inside this cheap ass living shield that makes people nearly invincible. If it means Itachi, Sasuke, and Madara had to step up their game to seem like an adequate threat I'd prefer it rather them chilling out in the safety bubble that is Susanoo.
