Nice idea with the support tier list thread so I thought we should make our own jungle ones too! I am a diamond player and I think it would be interesting for others to explain what elo they're in as I'm sure that can often attribute our opinions.
God tier: Shaco, Fiddle, Vi, Eve
Tier 1: Nocturne, Rammus, Lee, Jarvan
Tier 2: Amumu, Master Yi, Elise, Rengar
Tier 3: Sion (honest to god, you need to see this), Hecarim
Will update a bit more once I play a vs a few more or as them. Seriously though, Fiddle is so strong where I'm at. I have yet to face a bad one.
