The biggest problem with Riven is that she doesn't mana. Riven when she first came out had mana (she was actually given a mana bar but none of her moves costed mana). I think Riot actually originally had her use mana when they were creating her but she had such huge flaws in actual play that they had to remove it.

The fact that she doesn't use mana means, even if you outplay Riven, she doesn't have to worry about going oom. Imagine if she used mana - she have 0 sustain top, could only really on the first few minutes to win lane, and couldn't spam. Her problem is not her power at all, it is that she can constintly use that power that is the problem.

Riven is such a strangly designed champ: high power, shield that scales off AD, high mobility, low cooldowns, and to top it off no resource cost. These nerfs were needed.
