If you are just AFK farming the Jungle and every lane is losing from repeated enemy ganks.
You are mostly to blame for the loss. If the enemy Jungler has free roam of the map where you are not either ganking, counter-ganking, or counter-jungling at the same time, you caused the loss. You cant win 4v5 and with you in the jungle, 100% of the time, AFK farming, you provided nothing for the team except maybe a dragon or 2, maybe.
If you want to spend the first 15 minutes farming, go any other role besides Jungle and Support. Junglers need to look for gank opportunities and any other chance to get an advantage over the other team. Farming only your side of the jungle without ganking or pressuring any of the lanes is not helping.
