I am an adc + top main and I've been playing Draven since season 8. Im an oce player and I made this guide because I was feeling bored and wanted to share my experience and help new/old draven players out.

PROS:

-Insane damage output
-Can carry on all stages of the game
-Fun to play with
-Quite flexible with his builds
-low elo bully champ

CONS:

-Movement is easily predictable due to his q
-Requires a cash in to really carry
-8/10 difficulty to master

Main Keystones:

In the current meta, lethal tempo has outshone every draven rune because of the attack speed and range you get in long team fights. I've also started to love using this rune as it helps so much in kiting and finishing off enemies.

Conqueror is also one of my favourite rune to run on draven due to the extra ad and heal it gives in teamfighting, it works well against all kinds of matchups and provides better results than Pta and Dark Harvest

Press the attack I like to run into squishier line ups, such as ashe and ezreal and miss fortune. The only problem is that this does not provide as much sustain as conquerer does in team fights.

I take dark harvest when im confident in the team comp im going into and i know i am going to get alot of stacks from the enemy laner. This is more of a for fun rune.

I don't take hail of blades anymore, but I would recommend this for Draven beginners as it is very easy to work with.

Mini Runes:

Triumph is neccesary to survive teamfights and gain that little extra gold from kills and assists

Bloodline has started to become more important as it helps draven survive more.

This rune helps you survive and do more damage in close fights where your being targeted the most, draven will always be the main threats in fights because of your potential to snowball and carry games through your damage and passive. I've been running this 95% of the time but if your versing 2-3 tanks, cut down is also great

SECONDARY RUNES:

Absolute focus works well with draven in all stages of the game. If you play very mobile and position yourself properly you shouldnt drop below 75%, allowing you to maximize your damage

Gather storm is so good on Draven, it helps him scale AD in long games so even if you are behind, this rune will help give the tiny boost you need to do damage to their adc

Other options:
I take this sometimes depending on the team comp im versing, if I'm against a bunch of ***sasins or mobile champ, I would take this to help catch up or gain that short burst of movement speed to get away.

I also take this sometimes depending on the team comp im versing, if I feel like I need the extra lifesteal in lane I take this paired with legend bloodline .

Catching axes more efficiently

In case you didnt know, if you use a to auto attack then right click towards a position straight after, your q will land in that area. I recommend going into practise tool and trying this out until you can catch your axes without burning all your mana
Play Video Cashing in your passive

The way I cash in is by consistently catching my axes until I can reach around 120+ and look to all in the enemy. Draven is arguably the strongest early game adc if not, the strongest level 2 champ in the game, utilising it early with an engage/cc support helps alot and this is where cleanse and exhaust come in handy.

Early game:
If your support is alpha asf and has a brain, contest for level 2 and all in, draven has one of the strongest level 2 all ins in botlane and getting that early kill/gold lead will help alot with the lane.

If your against a harder matchup, i suggest just try and stack up until you hit 6 and then go for the all in. Before doing this, you wanna look to bait some summoner spells in the earlier levels

Mid game:
Mid game if your ahead, you want to extend your lead by taking out the rest of the tier 2s and showing up to objectives like rift and drag. Also if you can, begin grouping with your team to deal alot more damage in team fights. At this point you should have your 2nd/3rd item.

Continue playing for map objectives and baron so you can try to close out the game. There are some situations where you need to split and hard push the sidelanes to apply pressure. It should go something like 2-2-1 (2 top, 2 mid and 1 bot) or 1-3-1 (1 top, 3 mid and 1 bot) in this case, you always want to be mid because you can rotate as draven into either side faster if a fight breaks out or your jungler wants to contest an objective.
