Why you shouldn't play adc
Okay so hear me out, if you're playing botlane and you pick an adc, you're probably playing a champ that will have 0% chance of surviving a one shot burst from most assassins in the game and probably scale hard AFTER 30 minutes. Considering that the average game ends by 25 minutes, you're basically dead weight.
TLDR : If you're going bot just go double top at bot (like Cho and Swain)
