U.R.F does not like riven?

I'm not sure about others but I just played Riven and stomped hard. LOL. Maybe people are too focused on trying to get the other OPs ( ftw) to remember good ol' Riven </3 Plus, one of the greatest things about URF is no mana cost so Riven isn't really that special since she already has that . Might as well take this oppurtunity to play a champ that has early game mana problems amirite? :D

i've seen tons of rivens

She is nice, but destroys keyboards.

Riven already is manaless and has low cooldowns and has high mobility in a normal game, therefore urf doesn't help her very much

She does well, but she's nothing special. If her team can make use of her CC she'll destroy. Since she can spam that all game long.
