These 20 minute barons show how bad the damage creep is.
Back when I started league, we didn't have to worry about baron until 35 minutes in because baron was stronger as well as damage wasn't absurd back then. Nowadays if you show 2 people botlane or have 1 dead and 1 botlane, you know that the enemy will rush baron in 12- seconds and then you will be forced to play very defensive for 4 minutes and after that, you will be playing from behind.
