Because god damn this champion is unfair to play against come late game. I literally got one-shotted 25 minutes into my game because our mid, jungle and bot fed their asses off.
And I couldn't do anything about it because no matter how much magic resist, he will still be able to out damage anything.
He needs a cap on his passive because letting him continue to stack into over 1000 AP is beyond broken.
Please put this into effect, Riot, for the sake of all the players who have to play against this crap.
