Well am no one that play's Draven only. I can play draven everywhere adc, top , mid or even support if i have too.

Since i watched Tyler1 play league i realised that normal draven sucks when u are toxic and building yolo early/mid game items it's fun. Well youmous makes u strong before 18 min after that it's pretty much useless and u will be useless if u don't get item on draven before that. WHY DRAVEN DOES NOT NEED BERSERKERS? CAUSE HE HAS HIS W :)

Am currently platinum 1 playing only draven last seasons i was silver and gold but then i played draven only (mostly)

PROS
+ Draven is fun
+ Really cool when u learn some mechanics (for example use ur E before flash)
+ Good at climbing
CONS
- Easy to play hard to master
- If u are new to draven pretty easy to perform badly
- If u have bad support u will have bad game
- Really easy to cancel auto attacks

Draven has many cool mechanics that new draven players don't realise (not everyone but u know :) )
SOME EASY MECHANICS
- U can reset ur axes on turrets, Vision plants, heal plant's.
- Resets W when catching axes.
- When u use ur ultimate u can cast it back
HARDER ONES
- u can control ur ultimate by ur movement For example with ur flash
- Throwing E before flashing make u do more dmg cause of closing range gap and slowing ur enemy.
There are plenty more but it supposed to be an build guide and dunno cya or smth eheh===>xd
