Something needs to be done to make jungle more desirable to play at Diamond+
Nobody wants to play jungle. I can't even queue with it as my secondary, because I'll get it in 9/10 games. Even if I don't queue for it, I still have to play it in maybe 1/5 games, because someone was auto-filled to it.
It's not surprising, because it's a shitty role for solo queue due to the fact that it's heavily dependent on all four players on your team, and the match ups are entirely binary if you factor out team mates. Success largely requires the enemy team to play poorly, less than it does you playing well.
