Face it: Riven will never see direct nerfs.

They're just going to blame the items that she uses (which btw she can build just about anything with AD and make it work). Or they'll blame Conqueror (which btw she can use just about any other set of runes just fine lmao). Or maybe they'll try to buff the competition to compensate (although when they receive the same amount of success they'll get nerfed swiftly).

But they will never nerf Riven herself. Because she "takes skill to play" (despite her playerbase exponentially booming because she's gotten more forgiving to play and one does need to play her even remotely optimally to play her competently enough to still win games).
