It's 12 minutes, I'm slightly ahead at mid, and a 10-0 ADC just rotated into my lane
The ADC is ahead two entire items while I'm just finishing my first, and I have no way to defend my turret against it. The game is also completely over, without myself or top lane having even had a chance to impact it.
In a solo lane, the ADC likely would have only been 5-0, which is completely manageable. 10-0 is not.
Something needs to be done to revoke bottom lane's ability to irrevocably throw the game prior to the 10 minute mark. The winning side generates WAY too much of a gold advantage.
