Riot feels that "waiting for them to make a mistake" is not the proper way to counter someone...

Then they have the assassin update and we have issues with champions like and

Now i know what you are thinking "but Kats win rate is garbage right now" and i agree, but the biggest problem with Katarina now is her mobility is limited ONLY to her making a mistake. Keep in mind I am a mid-lane assassin main, and I just can't seem to wrap around how hard it is to lane against this champion now. Thinking like Yasuo's lvl 2 where you have to be passive af, now with Katarina once she hits lvl 3 your lane is over (unless she misplays ofc) I know i know, GIT GUD. i get it, im bad, i can handle that. But with the current state of her kit the only way to beat Katarina is to wait for her to misplay.

Now to jump on the "i hate vayne" bandwagon. Incredibly unbalanced champion (imo) with the changes to invisibility AND along with the changes of the assassins with giving "their prey" more time for counter-play. Now the hypercarry is practically unstoppable (thus the high pick rate). With the changes to invisibility the only way to beat Vayne is for her to misplay on a tumble. NOT TO MENTIION how fast she blows ppl up late game - But hey, lets add a ton of windows of opportunity in for people to outplay assassins-
