Ok i know you love riven but she needs some resourse or she is too broken

I know people like riven alot, i do too, but hey i think she is too op. Her no mana , no energy kit is too op especially with those cooldowns that she has. I mean her abilities are give her crazy utility , stun and shield and late game the cooldowns also get reduced to where she can just spam that shit and not care about anything. I think energy should be proper on her, as she would have to wisely use her abilities and make them less spam able.
