So it's pretty much unanimously agreed that..
Champions win rates increase with play rate and experience.
Example- Yorick
How come for a champion that is supposed to be a monster in the hands of masters, Riven, she has an insanely low win rate for players with large amounts of games played?
I love her immensely, she's so fun to play. But lately again she feels like people just do her job better.
She's insanely squishy even with her shield and mobility, and quite honestly her damage is nothing special at all anymore. Tanks can burst carries in this day in age, full armor malphite for instance can 100-0 a carry while simultaneously being an indomitable monster.
Kled is tanky for free, Fiora has true damage, Olaf goes into a CC immune berserker rage, Yasuo can instantly gap close and apply massive armor shred. I could go on but my point is most fighters have better tools of the trade now. But you look at Riven and see horrible base damages, trades her own damage to use it as mobility, insanely low health and health regen for a melee, and really honestly telegraphed gameplay. Yes other champs have weaknesses too but more and more people seem to be agreeing that Riven isn't strong anymore. People think she's a joke and honestly it's pretty shitty.
Yeah she can 1v1 well, but it's nigh impossible nowadays to apply the impact and pressure a champion of her caliber and learning curve should be able to in teamfights with the insane amounts of CC and damage being tossed around. Even with QSS you're likely to die before you can reach a back line, even when flanking.
She's in an ok state right now, much better than the roadside ditch riot left her in pre season and most of season six, but she also feels lackluster at the same time. She kind of feels like the spark that made her Riven is gone. And I really don't think this buff is gonna make her strong, not to the level she should be.
TLDR: I think Riven isn't rewarding to learn anymore compared to a large number or other picks and really could use some loving other than just an ult buff. Fun, but not reliable or rewarding.
There is nothing that can justify such a large experienced player base having such a low win rate at 125+ games, hovering around 50% is pathetic for that kind of experience.
