What happened to this game? (snowballing)

What happened to the lol where games would keep swinging in either direction? Made games more engaging, and fun, and always felt like you had a way out. Now? One team gets a few early kills. Half your team rages/flames and say the game is over even if its only 5 mins in. The enemy team continues to snowball because not only your team isn't working well together, but for some reason they made it so the way damage/defense scales, if you get slightly ahead, you can start 1 shotting members of the other team. Damage is just so ridiculous at this point. Why does damage scale so exponentially? It's almost impossible to come back when you don't even have an opportunity for outplays. What happens when damage is so high, is that there is no room to outplay people, because you just die instantly. Whereas when defense and offence are even, you have SOME time to try and outplay. I've been playing since season 1 and this season by far has become my least favorite. Having a hard time even logging in to play more than a game or two because either my team completely dominates and I get bored because there is no challenge, or the enemy team is so oppressively fed that I feel helpless (alongside dealing with the immature/ignorant teamates that comes with being behind)

...Pls fix this. Nerf damage items, up their cost, change scaling, make defensive items better, just do SOMETHING.
