Why hello there. I am Andrew(also known as RNG Draven, DeX Carry, Draven4Charity or TripleAxe). I have been playing Draven(And mostly only him) since his release. I was in the Top10 Draven's in the world obn LoLSkill.net list on Season 4. I just wanted to share the knowledge that I have gathered over the course of years with everyone.(Should add more info)
I usually stream everyday on http://www.twitch.tv/draven4charity
I'll keep updating this guide and adding more info to it all the time, but I believe I have the basics written here

Draven is a High Damage carry. His main damage comes from his Spinning Axes(Q) which increase his damage output dramatically, but there is a catch(Get it? No? Continue reading then). You have to catch them... every single time you auto-attack using them. You can control on where the axe lands pretty easily, when you throw it, just run in the direction you want them to fall. Draven's W - Blood Rush, gives you attack and movement speed for a short period of time. The cooldown resets every time you catch an Axe. This can be used to gain an advantage over your opponents and for kitting. Draven's E - Stand Aside, is his only CC spell, that knocks the enemies to the side(Works with Yasuo's ult) and temporarily slows them. This can be used while chasing for kills or to escape a pursuit. And finally Draven's R - Whirling Death, is a Global ult, which when casted will go in a straight line (Like Ez's Ult), but will turn around after 0.5sec after hitting an enemy. It can be also cancelled by Draven. It has a good damage output and you can easily get people who are low all over the map.

I know most of the other ADC players don't like my playstyle. I use the High risk-High reward playstyle. I always rush for level 2 and whenever I get it, I start all-in'ing on the enemy botlane(They lose XP and a lot of HP because of this). I try to push the tower ASAP, get my core item build and just continue to push bot, so I could get some of the enemy jungle pressure off other lanes. This gives my jungler time to help mid and top. That's pretty much it :D

I had this idea about a sustain Draven build. I am running some tests and after that I will tell you everything about it here :P
