You will delete enemies from the field of justice with this build and Draven in general. To maximize damage make sure you catch all axe's and keep your Q up. And when chasing enemies or in a team fight after catching an axe make sure you use your W to speed you and and give you the attack speed buff. This will help your damage output and the amount of axes being thrown.

While laning most ADC's aren't a big threat. Mainly you have to worry about dodging skill shots from the enemy support so you don't get CC'd and bursted down. But this rarely will happen if you stay behind minion line and push, as is normal to always be shoved into enemy turret with draven as farming.

In team fights throw your ultimate (R) when the enemy team is stacking in a line for the most damage out put possible or aim for their carries to get the max damage and make sure it will hit on the way back. I do this after an auto attack or two to secure the kill.
