Yes, but that's your own problem. Don't blame your laners or say jungling isn't effective because just because you're a bad jungler. That's like me saying you can't play top lane and carry at low Elo because I'm a terrible top laner.
I will blame my laners when they spend approximately 95% of the game humping the enemy turret.
They don't always do that, granted, and the times they don't, hey, easy wins for the jungle. Which is largely why I was batting 50% before changing over to supporting.
It's just...they do. A lot.
Here's how good this XJ9 person is.
He's on blue, all lanes pushed the enemy to turret. He walks over to the overextended lane and walks out with a dead lane opponent. 15/0 by 20 minutes and the enemy team surrenders because they know turret hugging can't save them from this 2500 elo smurf that figured out the secret to killing turret huggers.
