Draven

Fun. Yes. OP? Nah. He's only really strong if he gets incredibly far ahead. Or just gets one kill :)

He has a strong damage kit but severely lacks things other ADCs have - mobility , a natural disengage/gapclose , utility , inherently high AS etc.

His trade-off is that you get a mild amount of utility from E, some an AS steroid you can reset but doesn't really help you escape a gank with W, a great modified AA steroid, and a global ult - all making for an extremely powerful kit with the highest marksman base damage in the game.

I wouldn't say he's crazy OP, but I would agree that he's the most fun of all the ADCs in the game. Having the free minigame while csing makes it a bit less dull.
