Players do not get better as you climb.
Take it from me guys. Just had a game where my bot lane gave first blood, double kill in a 2v1 lane, and the enemy team went against me as a 2v1 and counter picked me with Irelia and Riven (I was Gnar) There was also a 2v1 Mid, so that was a thing, and there was no jungler, but we never got objectives early. Welcome to low gold, high silver.
