wow this draven build completely changed my playstyle and i went from Silver 4 and a win rate with 2%, to challenger with a 99% winrate. Havent lost a single game since i started using this build, and running down mid potential is also great, i would perhaps recommend changing all your items for tear and boots of mobility but who knows. I will also say that ghost is also viable as second summoner spell after flash, for better kiting potential. You can also run cleanse for anti CC, which helps quite alot.
