I don't like Riven using energy, maybe it's a good solution balance-wise but lore-wise energy is unique to champions from Ionia (more closely to those trained in a spiritual order like the Kinkou order), but Riven is from Noxus. That place is about as unspiritual as it gets. I mean I guess you could argue that she uses a technique similar to Yasuo's (that whole wind-technique stuff) but Yasuo also doesn't use energy, so that isn't an explanation either.
