Successful players who use unusual roles/builds

I thought i would add this here because of all the attention it was getting on reddit. All credit goes to MrCinos for compiling such a great list. I wanted to extend the discussion to the boards. What do you guys think of high elo players using off meta picks/builds?

Ps - Im the Ap rengar main, feel free to ask me if you have any questions about it, or add me in game (P 1)
