Hitboxes

I was playing off meta jinx mid and I happened to verse a fizz. No big deal as long as he cant ult me it wont be an instant kill, ill just dodge it, but when the hitbox is completely broken, what am I supposed to do its basically impossible to not get hit if your even the tiniest bit close to it. Then there is thresh, or some reason even when the hook does not hit you, the hitbox acts like it did and pulls you in, I'm not sure if its thresh hitbox, or the players hitbox, or both but this needs to be fixed
