Misconception on Riven's high winrate

Just tossing some ideas here regarding her winrates.

Some says her winrate is still above 50 percent, therefore she is still broken.

I am here to share my thoughts on winrates.

this is my account link (somehow I couldn't create discussion with this account that I linked here)

I have played riven almost over 1500 games. Only riven. I just love playing riven cause she is fun to play around

I believe my winrate of riven this season is about 56 percent. I have played other champs less than 100 games I think

Given the massive time I spent on Riven, I don't think my 56 percent winrate is just because she is over powered.

and, here is the fun fact. I tend to lose game when I dont play riven. It is not a surprise right?

Some times, riven got banned. Or enemy team take her. Or simply we are all Ad, so I may wanted to avoid to pick ad top champ.

Then, I lose. maybe demoted. then if I get to play riven again. I may win.

I believe this is why riven winrate maybe high. I have winrate of 58 percent. If I keep playing, I should not be hard stuck at D4.

But, I am. I lose on other champ, and I win on riven. Staying in same rank D4, but I am keep boosting riven's overall winrates. I believe that a lot of riven players are like me. When I find opponent riven players playing against me, a lot of times they were riven one trick. ( from my experience about 90 percent of times).

I am not here to complain about riven's nerf, because I dont play her anymore. I am trying to play other champs now like cait, ryze, and jax

I guess I talked a lot, just tossing some ideas regarding winrate stats.
