The thing that annoys me about all of the Miss Fortune complaints is that people tend to not exploit her weaknesses but still say "omg mf ult so op" after they didn't even dare to pick a champion with strong CC.
Miss Fortune tends to either instantly win or lose in champion select in her current state. If the enemy team has heavy divers and crowd control (Leona, Rammus, Vi) or heavy damage assassins (Rengar, Zed, Lee Sin), or juggernauts (Garen, Darius) then she tends to struggle a lot. She has a lot of powerful counterpicks and I simply never see anyone picking against her. She has very obvious counterplay that with the rework did not change. Her Q, E, and Ult still all immobilize her, her W is extremely easy to break, and she is still a squishy and immobile ADC. Though someone will pick Graves into Miss Fortune and complain that her Q is doing a lot of damage and her ult is unstoppable.
