When are you going to nerf the jungle?
Jungle as a role disproportionately affects the outcome of the game, if your jungler is bad then you will lose unless everybody else on your team is better than the enemy team. Literally half of challengers main jungle just because its so easy to carry. Every ranked game consists of 5-6 jungle bans. Most junglers can easily 1 v 1 laners at all points of the game, how can ganking fail when junglers themselves already have enough power to practically solo kill?
