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?
Only 4 ADCs beat him or can go even in lane from experience (Ashe / Kog / Nilah / Cait), the other ones are favorable matchups or get wrecked , and the ones he beats get beaten super hard (Kai’sa/Vayne/Xayah/Jinx are free matchups for him)
