Anecdotally speaking, I’ve seen Draven more often being banned at least once if not twice in my lobbies whenever I queue ranked. But from checking stats website, he doesn’t seem too overpowered. What makes him such a powerhouse in the bot lane that requires a lot of bans?
Honestly it’s just the fact that he does a ton of damage + is really oppressive early, if he gets a kill and starts snowballing it can be hard to deal with sometimes + with his passive, a kill on draven early is more valuable than most other ADs
