I dont remember the last time I've lost a game where my jungler was feeding.

Probably because the game is mostly influenced by how good your jungler is, hence why it's the only role who can secure dragons, barons, and rift. It's also the role the primarily focuses on getting your team fed even harder than a support could ever do, unless you play a roam support like Bard, alistar, etc. Tbh, the entire role needs to be gutted to the fucking ground so the game isn't so one sided due to the "Who's jungler is better" meme.
