Difference between Riven and Zac, is that although riven's abilities cost nothing but CD, she is a melee fighter, so any use of any of her abilities puts her at immediate risk of incoming damage, while zac has some ranged abilities and anti-cc and his abilities don't cost nothing, they actually heal you with the blobs.
