List of Champions that feed on your Team but get 27 kills on enemy Team I'll Start...

Due to both people having what is known as "The Inverse Law of Shaco" (your Shaco is Bronze 5, your opponent Shaco is Korean Challenger) if team has a Shaco that is better/worse than average it creates a paradox as due to the law you can never face a bad Shaco or teamed up with a good one

Darius, Nasus, Fiora

but, shes so useless that even though she gets 27 kills she can't step up to my "support" sion build

I know that if I play these champs there is a good chance I will feed.... but I will be eating at an all you can eat restaurant with the enemy team on the menu (Not always grantee that I will feed but it is on my radar LOL)

Asking for examples on the law of Shaco and not including Shaco in your OP <.<

Wasn't this Nidalee's secret passive not so long ago? I remember those days....lol
