Is it just me or.....

Since the new patch, games seem to be carried by a singular lane, rather than a team effort. For example, I was playing jungle and I was doing fine (Zil jungle OP) However, my bottom lane started losing. It wasn't bad at first, but then, it kept happening. The snowball is too much now, giving teams advantages so high after one kill. One person carried that game. The adc. Nobody else got many kills, only him. Sure, some people got 1 or 2. We lost, completely got wiped. It was a 4v5. 3v5 because top lane wasn't attacking our top lane (for odd reasons) All because Lucian was basically able to kill 3 of us solo. I believe we started getting destroyed once we lost our first tower. They made the towers too squishy as well, being able to take down towers solo lane in a matter of seconds. This is negatively affecting the game because once you lose a tower, they get extra gold, snowballing, and soon they have an infinity edge or other items. Is it just me that is seeing this problem? One op char ruins the game. The games end basically 5 min after the first tower falls. Upvote if you see this as a problem
