Riven's win rates by division, a comparison
A lot of people have stated that Riven does not need buffs, and after looking at her numbers I can confirm they are correct. I've moved on from champion.gg. OP.gg is updated daily, and shows statistics for each division, although I prefer to use the data from the last month, since these numbers change constantly. Anyways, if you look at Riven's numbers, you'll notice she is actually very strong in challenger (55% win rate), but in bronze her win rate is extremely low (only 44%). These are not exact numbers, but I always round to the nearest whole number. Anyways, the higher the tier, the better her win rate is. Silver is 47%, gold is 50%, etc. These numbers increase every time you go up a tier, all the way up to challenger. From this data, we can conclude that Riven is a high skill champ who takes a long time to master. But on an experienced player, she is extremely strong.
