KALISTA NEEDS A DAMN NERF

I am so sick and tired of these new severely op champions being created my Riot. It's SUCH bs going up against Kalista because how the hell do you counter her? I just went up against a Kalista and a BLITZCRANK which is basically like saying 'gg we're done for, there's literally nothing we can do.' RIOT NEEDS TO STOP CREATING THESE SEVERELY OP CHAMPIONS. It leaves everyone else in the dark. How the hell do you counter Gnar as Varus, for example? Or if you're Jinx (relatively slow, both in attack and movement speed in the beginning of the game), and you go up against Kalista? I'm so infuriated I'm thinking about switching to another game. What really ticks me off too is you can tell the enemy team is being severely negative and toxic in their own game screen, yet you can't report them because there's no living proof. Riot, DO SOMETHING ABOUT THIS!!!!!!!!!!!!!!!!! Rant officially over...for now.
