User blog comment:StrategicMagic/Jungle Caitlyn - Because AD carries can jungle too/@comment-4636093-20120731223142

This is the 3rd time I've heard jungle Caitlyn mentioned, including the twice I've seen it done on the enemy team. Both times failed miserably in the game.

I can't say ether of these were accurate readings though. The first time they had a leaver on their team, and the 2nd time they had a leaver and a triple phantom dancer Jax.

I'm still sceptical of it working. I know how bad things were when Draven was being experimented in the jungle and looking at Caitlyn's kit makes her seem even worse (Draven has a rather good mana efficiency while Cait has mana issues galore, Draven has marginally more base MS, Draven's a better dueler, etc).

If it works then it works and nothing could ever convince me to not accept something someone's good at, it's just not something I'd try myself.
