Try to shove in your lane and get lvl 2 as soon as possible and all in, sometimes you might need to wait for lvl 3 if the enemy adc has an escape, sorta like ezreal or lucian.

Play aggressive, your draven, you lifesteal for the damage you deal, it dosnt matter if they have like a leona support and a jhin adc, learn how to dodge jhin w and then go all in on him. ESPECIALLY if you're fed.

Farm. ADC is all about farming and draven takes advantage of this fact with his Q. it's really easy to farm as draven because you do like half a minions hp bar lvl 1 and at like lvl 6 you can two shot a melee minion.

Runes are simple, you take 9 Lethality Marks. Why? Because its basically the old armor penetration except it scales with the enemy's level. It's not as snowbally as armor pen but it still does its job. You take 9 Armor seals because everything that can attack you does SOME form of Attack Damage whether it be auto attacks or spells. You take FULL attack speed glyphs, not 4 attack speed 5 mr, FULL. Why? Because it allows you to attack more frequently and lifesteal more with the keystone we're going to be taking. And for quints take AD to help you with CSing and early game damage.
