Every game is a snowball???

WHY?!?!?!? there is never close games anymore. its always 1 person gets fed and that team snowballs insanely hard. thats not what makes league fun. it completely negates any room for counterplay. first 7 minutes now completely decides game. if you are behind you cant comeback anymore. I know its an overexaderation. but this is the way most games are trending since the changes.
